About me

I joined Jan's group as a PhD student in October 2010 and have since progressed to a PostDoctoral position. I'm a mathematician by training and have built up a lot of experience in scientific computing, but the biology and chemistry is still a little overwhelming at times.

Outside the office, I'm a keen hiker and chess player.


My research focuses on the ecology and evolution of microorganisms. During my PhD, I investigated the evolutionary origin of aging (published here) and statistical tools for quantifying interspecies metabolite transfer - a form of cooperation between microbes.

Since submitting my thesis I've taken on eGUT, a project aiming to model the digestive system in silico.
