For the first time the Heidelberg Laureate Forum will take place. About 40 Laureates (Abel Prize, Fields Medal, Nevanlinna Prize, Turing Award) will attend the forum together with 200 young researchers. For a full week Heidelberg in Germany will be the hot spot of mathematics and computer science. Six of the young scientists told us about their current research and their expectations before the meeting.

Name? Ella Gale

Nationality? British

Where are you based? I'm currently based in Bristol jointly working at the Bristol Robotics Laboratory and the University of the West of England

What is your current position? Research Fellow

What is the focus of your research? I am interested in unconventional computing, which is centres on using unusual phenomena for computation and understanding the natural world as computation. My specific area is memristors. These are novel electronic components that are a consequence of symmetry in electromagnetism. Synapses in the brain (the connection between brain cells through which learning takes place) have been found to work like memristors. Part of the neurons (brain cells) which is involved in neural signal transport can possibly be modelled by memristors.
Thus, I am interesting in building a neuromorphic (brain-like) computer from memristors. I think that the lack of success so far in making truly intelligent machines may be because we have so far lacked brain-like components to make it: however, even if memristor networks fail at this task, it would be interesting.

I'm also interested in using bio-inspired approaches in computing as a source of novel algorithms and approaches and understanding how biology fits in within computation theory.

Why did you become a computer scientist? My degree was in Chemistry, but during it I drifted towards the theoretical end culminating in my master's project which involved stochastic theory and my first simulation. After that I was hooked, I found it wonderful to be able to make a model and investigate it theoretically using both analytical techniques but especially by doing simulations which allows us to take the model apart and understand it. My PhD followed on from this, I worked using computational simulations to understand chemistry and I was interested in computing at that time because of its usefulness to the physical sciences. For my post-doc I switched from doing computational chemistry to using chemistry to build computers. In this role I was able to go deeper into computing, specifically computability, computer hardware and artificial intelligence.

I think I was attracted to computer science because it is a new field with wide-open vistas and there is a lot of room to be a generalist, in fact a general overview is necessary for computing in a way that it isn't for the natural sciences. The idea that computational theory can explain life is one I find very interesting and exciting.

Anything like a favorite project? My favourite project is usually the one I'm currently working on! I've enjoyed designing and building logic gates with memristors, because this allowed a lot of creative thinking about what exactly logic is and how it can be implemented. I also enjoyed deriving the analytical theory for memristor operation based on fundamental electromagnetic theory, and it was very gratifying when it worked well.

What about your life beyond research? I write sci-fi novels, I've penned 7 now (of a series) and I'm working on editing them and getting them published. I'm also a keen photographer, especially black and white, infrared, lomo style, landscape, and, due to attending conferences, travel, of course. I also run, swim and practise sword fighting and latin dancing.

Why did you apply for the HLF13? I have ideas about computing that I am eager to discuss and it seemed like a wonderful opportunity to discuss them with great scientists.

What do you expect from this meeting? I'm expecting to have many interesting conversations! I'm hoping to learn many interesting things about computer science and mathematics, but I'm also interesting in learning about the job of being an academic scientist from people who have made a big impact in their areas. Perhaps I might meet some future collaborators among the other delegates.

Do you have any Laureates on your list, you would love to talk to? I tend to prefer serendipity, you can put yourself in the position of meeting people who might inspire you to something, but rarely can you say in advance who or how, so I shall probably try to talk to everyone!
