Profile

I was born in Cambridgeshire, but spent my very early life in Hong Kong and now live in London studying at Imperial College.

When I’m not struggling through physics calculations you’ll often find me doing some kind of sport: I love to run and cycle when the weather’s good, and when it’s not so good I try my hand at gymnastics. When I need to recharge I like to drink coffee and chat with my friends, or read a book. I’m currently challenging myself to read books that I wouldn’t normally pick off a shelf, so I’m open to any recommendations!

I study a type of particle called a “magnetic monopole”. All the magnets we’ve ever found in nature have a North and a South pole, and you can’t split the two — if you cut a magnet in half you get two more magnets, each with North and South poles. However, a lot of the proposed theories describing the universe predict the existence of monopoles: as you can probably tell from the word, one of these would just be a North or a South pole on its own. If we can find these particles, we’ll be able to work out a lot more about the universe beyond what we already know.

At the moment we don’t know very much about how these particles behave (if they exist at all). We have some equations that describe them, but they are very difficult — sometimes even impossible — to solve! Trying to do them with a pen and paper would take hundreds of years — this is where fast computers are very useful. I write programs that make use of a computer’s ability to do billions of calculations a second, which lets us make sense of these equations.

If we can build a reliable model of how magnetic monopoles behave, we might be able to work out why we’ve never seen them. It might be because we’ve never built an experiment powerful enough. It could turn out that we only need to look a little bit further, or it could be that we’d need an experiment the size of the galaxy!

I’m quite an early riser, so I’m usually up by 7 o’clock. If I’m feeling fresh I’ll go for a cycle or a jog before work. I don’t have specific hours I have to be in the office, but I normally try and get in at about 9. The flexible hours mean that it’s easy for me to work shorter hours on some days and longer on others, so I can fit my work around the other things I’m interested in.

I spend most of my time at work in an office at my desk. I normally do rough calculations with pen and paper, or on a whiteboard, then for more “heavy-duty” work I fire up my computer and get programming. I meet with my PhD supervisor once a week, where we discuss the calculations we’ve done so far, and decide which calculations to do next.

Aside from my research, I also do some teaching of younger university students, either in a lab or a computing suite. I also attend “seminars”, which are like small lectures where a speaker comes to talk about their current, cutting-edge research. These help scientists keep up with what other scientists are working on, and ask each other questions about their work. There’s normally tea and biscuits afterwards too, which really helps to break up a long day!

Most days I finish work between 5 and 6pm, when I cycle home for dinner, and spend the evening relaxing or socialising with friends.
