Cybersecurity: Humankind vs machine

Specialist researchers at Bristol are investigating the security of systems and the inputs required from human users.

Most people, when asked what cybersecurity is, would answer by saying that it’s making sure we stay safe online, by using strong passwords and up-to-date software. But human behaviour also has a large part to play.

Awais Rashid, Professor of Cybersecurity, is researching both critical aspects. His work investigates the security of that which we might consider to be obvious: computers, mobile phones, Internet of Things devices, as well as systems that are embedded in our critical infrastructure such as water treatment plants and power grids. To understand how people might add value, he also looks at the human component of cybersecurity – how attackers attack our systems, how we detect such attacks, and how we respond to attacks.

One of the things he’s analysed is how people make decisions around security. Because a lot of these decisions are about critical infrastructures there is a lot of confidentiality around them, making it difficult to get the information required.

He and his team devised a game which allows people to discuss how they make security decisions in a general context, without referring to their organisation. The game is effectively a set of building blocks and it represents a utility infrastructure. A lot of the gaming around cybersecurity is about attacking systems and learning from attacks, but Professor Rashid asks people to play the role of defenders, and to collectively make decisions around how to deal with the attacks.

Good patterns included attempts to balance between security priorities, open-mindedness and adapting strategies based on inputs that challenged one’s preconceptions.
Bad practices included tunnel vision, that is, disregarding information given by the environment that did not fit one’s self-proclaimed ‘security expertise’ and focusing excessively on expensive technological solutions while neglecting basic security hygiene. ‘In some cases, you can have a very high-tech network monitoring device, but if your employees are falling victim to social engineering through email, then your network remains vulnerable to attack,’ Professor Rashid says.

In some cases, you can have a very high-tech network monitoring device, but if your employees are falling victim to social engineering through email, then your network remains vulnerable to attack.’ Professor Rashid, Professor of Cybersecurity. 

The human element

Professor Rashid is not alone in wanting to develop a better understanding of the human variable in cybersecurity. Dr Emma Williams, who has a background in psychology, a doctorate in deception, and a career that has included time spent working in both the public and private sector, is interested in what makes us engage in secure behaviour online. Dr Williams is conducting her research in her position in one of the newly created Vice-Chancellor’s Fellowships.

‘My research looks at how we can ensure that users are engaging in secure behaviour online,’ she says. ‘And understanding that means answering a range of questions, such as: are we more susceptible to so-called phishing scams at certain points in time? And can our devices adapt to these potential vulnerabilities? For example, if your device can detect that you’re busy or distracted, can it send a request to update important software at another, more appropriate, time?’ By looking at the ways in which people make decisions with regard to their own online security, Dr Williams aims to answer some of these questions.

One key issue is the simple idea that security must not be burdensome. Professor Rashid believes it is security experts who must lower the burden on the user. ‘We can’t have people changing passwords every few days, we can’t expect people to remember 30 passwords. Security is seen as a barrier, and as researchers we have to make it more seamless. We are looking at how the design of security systems acts as a barrier to usability and what can we do to empower users.’

Historically people think cybersecurity sits in the realm of Computer Science – that all you need to do is create an algorithm and everyone is secure. But a lot of these algorithms are based on mathematical ideas.’  Professor Oliver Johnson, Professor of Information Theory.

The mathematics

Bristol’s School of Mathematics will be offering a new MSc in Mathematics of Cybersecurity in autumn 2018. Oliver Johnson, Professor of Information Theory, says, ‘Historically people think cybersecurity sits in the realm of Computer Science – that all you need to do is create an algorithm and everyone is secure. But a lot of these algorithms are based on mathematical ideas. Bristol’s MSc programme will be unique in the UK because it is hosted in the School of Mathematics. Cybersecurity is a key area of emerging importance. With an Academic Centre of Excellence in Cybersecurity in Bristol, and our refurbished and expanded Fry Building giving us a lot more space for Mathematics, we have the platform for new, forward-looking courses.’

The new MSc will offer students the opportunity to prepare for future threats to encryption, such as quantum computers. Professor Johnson explains: ‘Encryption on the internet relies on the idea that factoring big numbers is hard. It’s known that quantum computers can do this efficiently, once somebody builds one. We’re not there yet, but when planning ahead, maybe the algorithms in use now aren’t secure long enough into the future. So, by including quantum computing on this course, students will be able to consider what the next generation algorithms could be.’

Professor Johnson goes on to add: ‘I don’t think it’s going to be a case of a quantum computer on every desk, but for certain high-level transactions, we need to have these quantum-secure protocols built in. But that’s part of the excitement, looking to the future.’

And it makes Bristol an exciting place to be, particularly with regard to the new Temple Quarter Campus and the Quantum Technologies Innovation Centre that will be hosted there, with cybersecurity one of the topics that has been identified for the new campus.

‘I think it’s clear that a lot of the exciting applications, driverless cars, 5G phones, healthcare, will be generating vast amounts of data and it’s going to be absolutely imperative to ensure that data is protected. It’s a huge challenge, and it’s also one of the exciting things about Temple Quarter: we’ll be looking at big problems that require a commonality between thinking and approaches,’ says Professor Johnson.

Alongside the benefits of collaboration between industry, government, and the University, is the opportunity to have an arena where not only technologists will look at cybersecurity. The new campus will have social scientists working alongside legal experts and ethicists, for example developing thinking around questions such as: if someone is hit by a driverless car, who’s responsible? The passenger, the person who wrote the code, the person who sold the car?

There’s a growing network of connected devices, so whereas in the past people may have thought ‘I can opt out of the internet’, now the internet is so ubiquitous, that’s not possible. Protecting that information is a huge challenge.’ Professor Oliver Johnson, Professor of Information Theory.

Though they may not conform to our preconceived notions around cybersecurity, these questions are becoming increasingly important. ‘It may have been in the past people thought of cybersecurity as the computer on their desk, but as the Internet of Things takes over it’s your fridge talking to your smart home hub,’ Professor Johnson says. ‘There’s a growing network of connected devices, so whereas in the past people may have thought ‘I can opt out of the internet’, now the internet is so ubiquitous, that’s not possible. Protecting that information is a huge challenge.’

And how is Bristol helping to keep all that information safe and secure? We’re working to better understand human behaviours around security, and decision-making processes. We’re developing new cryptography techniques, and working on stronger software engineering. We’re studying vulnerabilities across human and technological platforms. What’s more, the University has huge strengths in mathematics, computer science, cryptography, and engineering. And with our new MSc we’re making sure that the next generation has the skills to tackle the security risks we have yet to imagine.

Back to the future: reinventing libraries

Traditional notions of libraries are changing. The University has announced plans for a new £80 million library to be built at the heart of the Clifton campus – we’ve collected opinions on what the future of university libraries will look like.

Why does Bristol need a new library?

It’s been a long-term dream of the University to upgrade this library. The Arts and Social Sciences Library is quite old now and if you consider when it was built, a lot has changed: how students study, the resources needed, the technology, their interaction with each other. We are really excited about Bristol’s new £80 million library development at the heart of our Clifton campus. Ultimately, students are here to be educated and it’s important to invest in quality facilities that inspire innovation and discovery

My own background is in History, English and Geography, so I’m very conscious that the library is a laboratory for Arts and Social Sciences students. It will function as a community and a collaborative space for students, where they can do self-study but also interact with their peers. It will be a library for the whole University, and provide an opportunity to step up our provision for students. Fundamentally it will support the educational experience, where learning will be extended through exposure to new ideas, space to reflect, and of course books will be front and centre. The new library will also have a gallery space, which will enliven the academic experience and exposure for Arts and Social Sciences students in particular. Students at
Bristol have access to incredible academic and cultural materials that many other universities are not able to provide. Gallery space, showcasing and celebrating our University’s unique special collections, will help to make the most of them.

We plan to increase cultural collections for display too. We have such rich treasures: a strong feminist collection, a rare book collection, a world-class theatre collection and so many other fascinating manuscripts and archival documents which we really want to showcase. Gallery space will help our collections to become something that the whole Bristol community will be proud of.

One of my aspirations is to advance a fantastic digital experience for students. We’ll be introducing a new cataloguing and search system for library items which also links to digital resources. Students will be able to search and access online articles that the University holds subscriptions for. All this will be available via an app on their smartphones.

The library will be inclusive, accessible, inspiring, adaptable and flexible to new ways of learning and technology, and sustainable. It will be built to last and to complement the surrounding heritage. Bristol is one of the world’s greatest civic universities: it’s always been a leader and beacon of excellence, particularly in research. We all aspire to build on our inspirational teaching and further improve the student experience, and having recently moved from the University of Melbourne to take up my post at Bristol, I’m really looking forward to realising our shared vision for this wonderful new library.

Why is the design of a library so important?

The library will be at the centre of the University’s vision for its Clifton campus to be the welcoming ‘heart’ to the University – for students, staff and members of the public alike. It will be a space for connection, with ideas and with others. Digital technologies are linking us more than ever, but we also appear to be more fragmented. Libraries are quintessentially democratic urban gathering places where an increasingly diverse user can connect for their own needs on their own terms. We produce ‘democratic architecture’ – architecture that focuses on the needs and experiences of the people who use the buildings and spaces we design. A place where diversity is valued. With each project, we observe the social habits, needs and the context of the community where our libraries are built.

Libraries are in constant evolution and being at the forefront of this thinking is essential to doing the best work. We have extensive global experience designing libraries at Schmidt Hammer Lassen and our work has been honoured with 16 international awards. Designing libraries of the future is unique because of the need to adapt to shifting human behaviour in terms of how we study and gain knowledge. We are developing the way we think about libraries towards what we refer to as ‘collection to connection’. How do we design libraries that both collect knowledge and bring people together?

The foundation of our creative approach to designing libraries is the concept of a third space that lies between our homes and workplaces. The urban sociologist Ray Oldenburg says the third space is vital for civil society, democracy, citizen engagement and a sense of place. We agree. We believe that architecture affects lives. We’re not interested in building for building’s sake – we’re interested in making a positive difference.

Libraries make a difference in our lives, in connecting us. With the University’s two iconic buildings, HH Wills Physics Building and the Wills Memorial Building, the new library will stand out as the gateway to the campus, a beacon of knowledge, representing the University of Bristol, being visible from all around the Bristol urban skyline.

What does a university library mean to you?

Inspiration. I came to the University in 1971 when the world was vastly different. I used the Wills Memorial library and can recall the hush of the busy monumental reading room, the hunt for a seat in the many alcoves. The impressive backdrop of the library with its high ceilings and formal wooden furniture was inspiring. We seemed to learn just by being in it. Back then all the resources were printed and we used a card catalogue to locate them. Although individual private study was the main mode of learning, the library was still a social space in the sense that there was an unvoiced fellowship among the hardworking users.

Although I was the first person in my family to enter higher education, I was no stranger to libraries. I grew up with the public library as a second home, secured a Saturday job shelving books, and worked on the service counter when I was a student. I learned valuable lessons about delivering face-to-face library services. This stood me in good stead throughout my career as the
University Librarian and Pro Vice-Chancellor at the University of Leicester including overseeing the £32m library renovation project there in 2008, which went on to win numerous library and architectural awards.

Some years ago, pundits were predicting the end of libraries in the digital age, but there has been more investment in academic library buildings and higher use of those facilities than ever before. Far-sighted institutions are demonstrating that libraries have a unique role in expressing and embodying the mission of the university.

It’s thrilling that Bristol sees the library as the hub of the Clifton campus and significant investment has been earmarked to support this conviction. It’s good to hear that extensive consultation on the detailed plans is to take place too – the most important and stimulating part of the project if the library is to become truly the heart of the University. The vision of libraries, evident when I was at Bristol, endures in the digital age: an inspiring environment to support learning and the creation of knowledge.

What will a library in the future be like?

Since I was six years old, I’ve been fascinated by the past. I went on weekly excursions to the library and read everything from Ancient Egypt to the entire Nancy Drew series. I was determined to be an archaeologist and thanks to AHRC funding I’m now doing a PhD in historical archaeology.

But so much has changed since I was six. As a mother and part-time distant-learning student there are so many challenges to overcome. My hours are bound to childcare, which in rural Wiltshire is pretty restrictive moneywise and timewise. I need to incorporate archive visits, fieldwork, and teaching, and last semester required military organisation of grandparents, friends, afterschool clubs, and transport. I’m grateful that the library can post me books when I need them, but now we have the internet, lots of things are available online too.

To study the past I’ve had to dig even deeper into the future. I love the countryside, but it has a huge transport problem, which makes travelling into Bristol incredibly inefficient and impossible if you’re on a tight timescale. Technology has been essential in enabling me to pursue my passion without sacrificing time with my children. But it still has a long way to go.

My dream library would exist in two places: virtually and physically. The resources I need would be online, such as datasets and historical documents. The University has a wonderful stock of hidden knowledge held in documents and collections it’s built up over many years, and it would be great to access these more easily. Academia is also increasingly called upon to engage with the public, which can be difficult to find space for. A public-facing exhibition space is a perfect way to give postgraduates an opportunity to be involved in communicating our work. Finally, my
pie-in-the-sky dream would be an ad-hoc crèche.

My eldest daughter is now six years old, and we’ve enjoyed exploring books on topics like outer space and the Great Fire of London. By the time she goes to University I want to see increased inclusivity and accessibility in the digital and real world, so that everyone can benefit from the knowledge held and generated in these amazing places.

Spotlight on: Goh Siu Lin (LLB 1993), Malaysia

Goh Siu Lin (LLB 1993) takes us on a journey from Bristol to Malaysia, showing us how she got to where she is today as the first woman to become Chairman on the Kuala Lumpur Bar Committee.

I chose to study at Bristol for many reasons. It is well known for having one of the top Law faculties in the UK. I was drawn to the vibrancy of the student community and loved the iconic grandeur of the Wills Memorial Building. When I graduated I was the first lawyer in my family. While at Bristol I took up volunteering opportunities with Bristol’s Student Community Action and did ballroom dancing which enriched my student life. I also made friends of all nationalities and backgrounds – I love food and there were never too many dinner parties at Bristol, all with new and exciting flavours!

The key things that Bristol gave me were an excellent legal education in a supportive and enriching learning environment, a place for self-discovery, and many, many lifelong friendships. Upon my return to Malaysia I gained admission to the Malaysian Bar and practised for the next two decades at Messrs Shook Lin & Bok. Then when I became the first female to win the Chairman post on the Kuala Lumpur Bar Committee, I was exhilarated! It was as if I’d crossed the finishing line for a marathon.

I’m passionate about women’s and children’s rights and have written and advocated for more gender-responsive laws, policies and systems. My proudest achievement to date was being part of the intense lobbying and legislative efforts which crystallised in the passing of the Sexual Offences Against Children Act in Malaysia on 26 April 2017. If I had any advice for my younger self it would be to read more, to be more involved in Bar activities and to develop networks. I’ve now set up a small boutique law practice of Messrs Kee Sern, Siu & Huey and this, together with my responsibilities for the Kuala Lumpur Bar, keeps me on my toes!

The legacy of Physics lives on

In a year when we’re celebrating 100 years of some women getting the vote in the UK, Nonesuch takes a look at pioneering women in the School of Physics.

When Veronica Macmillan started life as a Physics student at Bristol during World War II, little did she know that over 70 years later she would be helping new generations of physicists with their groundbreaking work by leaving a legacy to the School. Taking advantage of the University of Bristol’s longstanding openness to diversity, Veronica started studying for her BSc in 1942 as one of only a handful of female students of the 100 or so in her year. Her father had died when she was just ten years old, but she did not allow the tragedy experienced as a young girl to derail her ambitions for a higher education. Today we’re well aware of the importance of bursaries and scholarships for amazing students who might not otherwise get the chance to study, and in the 1940s the need for this assistance was also recognised. Veronica was awarded an Education Board Grant for her time at Bristol and travelled to study every day by bus from Bath.

Veronica fondly remembered Professor Arthur M Tyndall, known as the ‘Father of the School of Physics’. Of other lecturers she recalled that their handwriting could be difficult to read – one in particular making little distinction between his Us and Vs, thus making his formulae very difficult to understand!

As well as attending to her studies, Veronica played her part in the war effort, together with several of her fellow students who worked at the nearby Badminton Estate in South Gloucestershire. She recalled seeing Queen Mary who was sequestered there at the time. And while Veronica was working at Badminton, staff in the School were also doing their part, looking at the use of radar in the war.

While Veronica’s time at Bristol might have been overshadowed by the planes of war, 22-year-old Astrid’s research is looking at how to make civil aviation safer, as well as better for the environment. The Rugby native’s fully funded PhD work looks at ‘Non-destructive detection of corrosion on in-service gas turbine components.’

Although she loved her time at the School of Physics, Veronica did feel that she missed out on the social aspect of being a student, as she could not afford to stay in Bristol and went to and from her home in Bath. She did however manage to join her classmates at the refectory, and later in life could still recall the novelty of eating pink semolina pudding!

Upon graduating with her BSc in Physics, Veronica completed her teacher training – also at Bristol – and spent her life working at the convent school in Bath which she herself had attended as a child. Not only did she give back to young children as an educator, on her death last year she bequeathed a large legacy to the School of Physics, so that other bright young minds could carry on the work that she herself had so enjoyed.

One of those bright minds is Astrid Blee (MSci 2017), currently studying for her PhD in Physics, in an environment very different from that of Veronica’s. Despite seeing Bristol at its windy, rainy wildest on a post-offer day at the University, Astrid was still struck by how beautiful and inspiring the campus and city was.

While Veronica’s time at Bristol might have been overshadowed by the planes of war, 22-year-old Astrid’s research is looking at how to make civil aviation safer, as well as better for the environment. The Rugby native’s fully funded PhD work looks at ‘Non-destructive detection of corrosion on in-service gas turbine components.’ In a nutshell, she’s looking at ways to accurately detect ahead of time when an aircraft’s turbine blades are about to crack. Currently there is no accurate way of measuring this, so blades are ‘retired’ long before their life span has ended in order to meet stringent safety regulations. However, this does mean that it’s not great news for the environment to keep replacing the blades unnecessarily.

‘As soon as I came to Bristol I thought it was a place where I could live and thrive. What I really love about my area of physics is applied problem solving. I like taking a real-life problem and looking for a way to solve it.’

PhD student, Astrid Blee (MSci 2017)

So, what is it that attracted Astrid to physics? ‘What I really love about my area of physics is applied problem solving. I like taking a real-life problem and looking for a way to solve it.’ Unlike Veronica, Astrid has lived in Bristol since starting her undergraduate degree here and has been able to take advantage of the social life as well as academia. Her problem-solving mind extends from physics to one of her favourite hobbies – rock climbing. ‘I find it very mindful. You start at the bottom of the wall and your only goal is to get to the top. Working out how to get to the top, particularly when it gets more difficult – you can’t just use brute strength. You have to think about the problem and how you can solve it. And if that doesn’t work, try again.’

And what is it that makes the University of Bristol’s School of Physics so great? According to Astrid it’s the grand long-term vision that what seems elusive and theoretical now will go on to make enormous contributions to society: ‘Researchers who are working on new theoretical physics are laying the foundations now for what’s to come in the future. This maths can and will be applied to real world problems. You need a long-reaching view, which Bristol has, to be confident that it will be of great importance in the future. Take quantum physics. Laying the groundwork for that was started 100 years ago, and now we’re moving towards quantum computing and quantum optics and things that will start to have real world applications. Bristol is nurturing what may seem to some like a lot of theory, but we have the vision that it will be used in the future.’

Bristol’s School of Physics has been making its mark on science for over a hundred years, including turning out several Nobel laureates. It is recognised worldwide for its pioneering research in a wide range of areas, including: quantum mechanics, nanoscience, quantum information science, semiconductors, condensed matter and metal physics, cosmic ray and astrophysics, glaciology, X-ray interferometry and topological optics. Veronica’s legacy will ensure that future students of this esteemed School continue to push the boundaries of science ever further forward. Astrid is just one of many at Bristol taking on the challenges of the world we live in today.


We are holding an event this summer about leaving Legacy gifts to support Physics at Bristol. If you would like to know more about the event then please contact Jenny McGee on +44 (0)117 394 1045.

A friend indeed: Your Bristol stories

What’s a bit of swine flu between friends? For Friendship Day [30 July] we asked you about the friends you made at Bristol and you didn’t disappoint. From dancing in the street to film marathons and swine flu, here are a handful of the stories of why your time at Bristol became such an important part of your lives.

She gave me swine flu

Alice Webb (BA 2013) and I were both in University Hall in different blocks but we were on the same course. In our first week in 2009, she gave me swine flu and we’ve been inseparable ever since!

She has been my biggest cheerleader, my rock and my best friend for coming up to nine years and my life would not be the same without her. Too many funny stories to go through, but without all these hilarious years, we wouldn’t be where we are now having made it through some of the darkest times. With her and four other friends from languages, we have the best group of girls anyone could ask for.

Harriet Abley (BA 2013)

Half a world away

At Bristol, Kate, Kathy and I got on so well that we were inseparable.

I met my wonderful friend Kate Smith (MPhil 2015) on my first day in Bristol before term even started and met the lovely Kathy McInerney (MA 2015) through her who she bumped into at their student residences. We were all studying for completely different degrees (Accounting, Finance and Management / Medieval Studies / English Literature), but that didn’t seem to matter. We discovered so many fun things around Bristol like the Balloon fiesta, Harbour festival, and some lovely pubs. We spent a lot of time in each other’s kitchens, cooking together and board game nights or at the student union pub quizzes. Having these girls to always talk to has improved my life so much and although we are now separated by half the world between Hamburg, Boston and Houston, we skype as often as we can and this June they both made the long trip to attend my wedding which was the most special gift I could have asked for.

I cannot wait to see them again someday. Friends are the best excuse you can find to travel the world.

Lynn Baumgarten (MSc 2015)

Dancing in the street

Andrew Clarke, (BA 1992): the sweetest, funniest man. We rehearsed our ballroom dancing in the streets around St Paul’s; he made me jelly in Tom and Jerry glasses; his neighbour’s pet snake did something unmentionable on my jeans and the first time we met he asked to borrow makeup (to dress up for Halloween).

I miss him. Davros, if you read this, get in touch! Xxx

Sarah Anthony (BA 1992)

Where’s Dave now?

I would very much wish to get in touch with Dave Thorton. He did Maths and Computer Science in his first year, and when we met in 1968/1969 he ‘heralded’ from Cleckheaton. He and I were in Burwalls hall of residence during our first year at Bristol University. Without his friendship my first year in 1968/1969 at Bristol University could have been very different.

Damian Wozniak (BSc 1971)

Taka Taka cravings and watching every Bollywood Movie on Earth

Shreya Tandon (Meng 2015) and I have been roommates, batch mates and flat mates throughout the four years. This led to endless gossips, midnight Taka Taka cravings, sharing wardrobes (I used to dig into her wardrobe more often than she used to), gala times when cleaning our flat / room, dancing sessions, enjoying retail therapies together, watching every Bollywood Movie on Earth while enjoying meals together, last minute doubt-clearing sessions (she was obviously more studious), planning each other’s birthday surprises, immature arguments and endless moments of fun, laughter and joy. All these moments have been one of the best for me. She has taught me how to be a good and caring friend. Clearly we cannot be separated so we joined the same company after graduation and still live in the same city and in adjacent buildings.

Sanjana Narang (Meng 2015)

Women in engineering: Michelle McDowell, MBE FREng

Michelle McDowell MBE FREng (BSc 1984, Hon DEng 2012), studied Civil Engineering at the University of Bristol. When she graduated she became a structural engineer. As her career progressed she has led many high-profile and award-winning projects, including the refurbishment of the Royal Albert Hall. In 2011 Michelle was awarded an MBE for services to the construction industry and she is now the Chair of Civil and Structural Engineering at BDP. We spoke to her on International Women in Engineering Day 2018.

Tell us about a woman you think more people should know about.

If you are lacking inspiration, take a look at Helen Keller. Meningitis as a baby left her blind and deaf. In spite of this, she not only mastered the English language, but learned to communicate in French, German and Latin. At a time when Harvard wouldn’t admit women, she attended its ‘annex’, Radcliffe College. She went on to become a political activist, a vocal socialist and she marched in women’s suffrage parades. She certainly makes you think twice about complaining! 

We’ve come a long way in 100 years. What do you want to see changed next? 

I would like to see employers positively embrace flexible working, really embrace it. As someone who works flexibly, I think it’s a brilliant deal for employers who get excellent value for money combined with company loyalty. Of course, I benefit too from spending more time with my young children.  

What every-day act would you encourage feminists to take? 

Refuse to put up with unacceptable behaviours – brace yourself if necessary and challenge them. Make the perpetrators feel uncomfortable. They are in the wrong, not you. 

What do you love about being an Engineer? 

I love the tangible results of a very creative process – buildings which emerge from sketches and models, if well designed, can transform lives. One of my most inspiring moments was to return to a school I had designed and for the head teacher to point out a student who formerly played truant but who now not only attended but stayed on after school to do homework.

We’re asking staff, students and visitors to the University to answer our three questions. Watch our latest video.

Bristol’s pursuit of film excellence

Nonesuch takes a look at what the city and the University are contributing to the world of cinema and television in the digital age.

When you think of Bristol and the world of small and big screen, what springs to mind? Hollywood star and Horfield native Cary Grant? Aardman Animations’ Wallace and Gromit? What about the BBC’s Blue Planet and David Attenborough? Or maybe you just fondly remember curling up in front of the latest offering from the University’s Film Society during your time here.

‌Our alumni in the world of film and television include actors, directors, writers and special effects experts. They’ve won Oscars and BAFTAs and are seen as leaders in their fields. Even our University buildings have had a starring role. The 1990 BAFTA-award-winning film Truly Madly Deeply was filmed on location at our very own Goldney Hall, while 2006 hit Starter for Ten was filmed at the School of Chemistry.

Bristol’s reputation as a city of film continues to spread far and wide, and in late 2017 Bristol was designated UNESCO City of Film, becoming an official member of the international UNESCO Creative Cities Network. Dr Angela Piccini, from the School of Arts, said: ‘UNESCO City of Film status draws together all of the diverse film, television, and screen media activities across the city. Here at the University we actually teach and research across moving image forms in many Faculties, far beyond the Department of Film and Television and Faculty of Arts – from medical imaging, to computationally driven innovation, to the politics and power of media representation and the aesthetics of industry-facing practices. Bristol is at the forefront of moving image innovation and the creative industries.’

And in February this year our Chancellor Sir Paul Nurse FRS FMedSci conferred an Honorary Doctor of Letters upon Col Needham – who some have referred to as the ‘most powerful Brit in Hollywood’ – for his contribution to the film industry. Dr Piccini gave the oration for Mr Needham, who is the founder and CEO of the renowned website IMDb (Internet Movie Database). Formed in 1990 IMDb became a wholly owned subsidiary of Amazon.com in 1998. As a film buff Col wanted to build a portal of information on all things screen-related, where like-minded individuals could connect and share their love of film no matter where they were in the world.

Today IMDb has over 250 million monthly visitors, who go online to rate, review and read everything they can about films and TV shows from around the globe. Col talks about how Bristol has been so important in the success of the company, and why it still has its heart in the city: ‘We manage the world’s largest database of film and television information from Bristol. It’s a 250 million item database based in the city, and I don’t think the company would have grown the way it did had I been anywhere else. Bristol has been a city of technology companies and media entities for a long time. With IMDb sitting at this intersection of film and technology, when we need to hire we can find people with the right skills.’

As the University continues to grow and integrate its focus on technology and innovation, we look forward to continuing to enjoy Bristol’s status as a place for film to flourish.

Virtual touch

Fresh from winning the prestigious Queen’s Award for Enterprise for Innovation, alumnus Dr Tom Carter (PhD 2017), CTO and co-founder of technology firm Ultrahaptics, tells us about touching things that aren’t there.

Imagine if you could reach out with your hand and touch a shape in mid-air – a virtual object that you could feel, but not see. That might sound like science fiction, but it’s real, and it’s happening here in Bristol. Ultrahaptics’ technology, which is based on my PhD, uses ultrasound to create three-dimensional shapes and textures in mid-air.

I’ve always been passionate about interface design, the user experience, and making things better. Human interaction with things should be efficient and easy for the user. I’m sure I’m not the only who gets annoyed by parking machines with impossible instructions, or the way when you need to change radio station in your car you have to flail around for the button while trying to keep your eyes on the road.

That’s what our technology is all about – making the way we interact with machines easier and more intuitive. As our tech develops I’m excited about its possible use in so many areas. For now, though, Ultrahaptics has featured in trials of an interactive movie poster and was also part of an art installation at Tate Britain. We’ve seen our tech rolled out into gaming machines and featured as part of a Halloween show at The Magic Castle in Hollywood.

Founding my own company has always been something I’ve wanted to do. When I was studying Computer Science at BristolI was lucky to be in a department that was so forward thinking. I was able to take modules in things such as entrepreneurship, learning about business plans and how to raise investment capital.

The people I met and worked with at Bristol stretched and encouraged me beyond traditional departmental boundaries. Ultrahaptics also benefited from being part of the University’s SET Squared incubator, currently housed in the Engine Shed hubwhere Brunel used to work.

It’s great to see entrepreneurship become more firmly embedded in the University curriculum, particularly with the new Temple Quarter campus that will have innovation at its heart. I believe you can start a business from any background and it’s so encouraging to see this new way of studying come to life.

Futuristic healthcare

Biologist Sara Correia Carreira plans to build robotic skin, conducting research into the combination of robotics with bioengineering – just one of the ground-breaking projects being investigated by the first cohort of Vice-Chancellor’s Fellows. These Fellowships highlight the spirit of innovation and collaboration that is taking us into the future.

As a child I remember being fascinated by the robotic hand of Luke Skywalker in Star Wars: The Empire Strikes Back, and what he could do with it. Interfacing living tissues with non-living replacement parts seemed a tremendously exciting idea! But I never thought that today, as a biologist, I would get to work with an amazing robotics team in the realm of healthcare. I never imagined that human biology could work so closely with an area of engineering as complex and interesting as robotics.

As part of my research programme I am working on a way to engineer a living and moving robotic skin. Skin is something I became interested in very recently, while working on antimicrobial sprays and creams that can be topically applied to prevent infection of wounds. Through my work I discovered that it was impossible to test how well these creams and sprays would perform on the skin of an actual living, moving human – for example, would they slide off as the skin moves around? Would they penetrate properly as the body went through its natural motions? We cannot know, as there is simply no laboratory model of moving skin – the current models are flat and static, with skin grown as a sheet on a rigid plastic membrane.

My research aims to find a way to apply those mechanical stresses to engineered skin. Apart from making it a far more realistic model of skin, it could also improve the mechanical properties of the bioengineered tissue, so that it more closely matches the characteristics of real skin.

How am I going to make this work? Robotic skin! I plan to replace the rigid membrane with something stretchy, using soft robotics, to mimic the muscles that would be underneath real skin. The ability to bioengineer the skin exists and Bristol is making incredible progress with soft robotics. I will be collaborating with colleagues to create both. Then the biggest challenge of all will be finding a way of attaching the skin to the robotics underneath, which is what has never been done before.

Initially the robotic skin will be used to investigate whether the movement of medication across this model is different from the current static models. But it could improve people’s lives in other ways, for example burns patients who need skin grafts. With robotic skin we could test it under more lifelike conditions, making it less likely to rupture when grafted onto the patient.

To even attempt what I want to do I needed certain conditions in place – which Bristol readily fulfils. This project requires: an institution with a reputation for research excellence; world-renowned robotics and bioengineering facilities; and a willingness across faculties to work in an interdisciplinary and collaborative way. I will be working with some incredible colleagues here in different departments to make this project a reality.

When the call for applications to the new Vice-Chancellor’s Fellowships went out, I jumped at the chance to apply. My experience at Bristol doing both my PhD and my postdoctoral research had demonstrated very clearly what a unique collaborative experience could be had at this University. I did my first degree in Biology in Germany, where I’m from, and afterwards I was unsure if I wanted to continue with academia. My time at Bristol has shown me what wonderful opportunities are being afforded here, to researchers like myself who are excited about the advancements we can make for humanity. The research that I and other scientists are working on right now is uncharted territory. I’m grateful that Bristol is giving me the opportunity to do this research and make a real-world impact on healthcare.

Made in Bristol: Professor Weicheng Cui (PhD 1990)

Professor Weicheng Cui (PhD 1990) is one of China’s most remarkable scientists and a proud alumnus of the University of Bristol. The world-renowned pioneer of deep sea exploration had the opportunity to congratulate the latest graduates of Bristol when he joined the University as Distinguished Guest at its first ever graduation celebration in Shanghai, on Saturday 14 April.

The University of Bristol’s reputation for nurturing research talent is exemplified by Professor Weicheng Cui’s (PhD 1990) extraordinary career.

He is the Dean of Deep Sea Science and Technology at Shanghai Ocean University and was recently named a ‘science star of China’ by Nature magazine for his record-breaking work on manned deep-sea submersibles, including the Chinese Government funded Jiaolong.

‘I have always been fascinated by the idea of exploration and pushing frontiers. I chose to do my PhD at Bristol because it is a world-class institution which combines a strong research heritage with a pioneering approach to the advancement of human knowledge,’ said Prof Weicheng Cui.

In 2014 he founded Rainbowfish Ocean Technology Co Ltd with two fellow Bristol alumni, with the aim of building the world’s first commercial, deep-sea submersible fleet. Their ambition is to reach the deepest place on Earth — the bottom of the Mariana Trench, 11,000 metres down – by 2020. You can find out more about the project on the BBC website.

In recognition of the high value he and colleagues place on their University of Bristol education, Rainbowfish has maintained links with the institution by providing internships to Bristol students.

‘At Rainbow Fish we are concerned with pushing ourselves to the very edge – or depth – of deep sea exploration. To do this we need interns who share our passion and inventive spirit. I believe the University of Bristol nurtures these values and produces students who are well equipped to help us succeed in our mission,’ said Prof Weicheng Cui.

The company is just three years old so many of their Bristol interns haven’t graduated yet. However, Professor Cui is confident that when they do, there will be exciting opportunities for talented young scientists to follow his lead, pushing the boundaries of human exploration.

‘Since three years ago, both our research center and the Rainbowfish company have become places for Bristol students to do an internship. Now we have the capability to take 30-50 students every year. As an Alumnus of Bristol university, I really appreciate very much for education I received and I will do my best to help other students in need. I sincerely wish my University better and better!’
