Starting from 2017, I have been a co-founder and CTO at Labstep. Labstep set out to make scientists more productive and creative. So far this involved building a software tool at

Under the supervision of simulation masterminds, Mark Sansom (Oxford University) and Robert Best (NIH), I'm working on membrane protein folding.

I used to work as a scientific associate in D. E. Shaw Research, New York City. The focus of this work (among other things) were transient/cryptic protein pockets identified via ANTON simulations in phosphatases PTP1B and Ship2. The aim was to predict small molecules that would bind to these pockets.

I did my undergraduate work in Oxford, studying Biochemistry, earning an MBioch with honors and a medal from the Queen and Mick Jagger. My graduate project was in Groningen, Netherlands working on molecular dynamics simulations.
