   I am a Postdoctoral Fellow at the Australian National University's Mathematical Sciences Institute. Before coming here, I was a Research Associate at the Department of Mathematics, Imperial College London. I have received my PhD in October 2015 from the University of Cambridge, where my advisor was Dr Jacob Rasmussen. In the spring of 2016, I have visited the Max Planck Institute for Mathematics in Bonn, Germany.

I am broadly interested in geometry and topology. My research focuses on knot- and link homology theories which also have deep relationships to representation theory and mathematical physics.

Extracurricular activities:

Sailing: I am a skipper in the Cambridge University Yacht Club and I have been a main sail trimmer in the Cambridge University Yacht Racing Team, for which I have received a Cambridge Half Blue.
Running: In October 2017 I was part of a team from the Mathematical Sciences Institute which won Division 5 of Inward Bound, an overnight adventure footrace over roughly 50km in mountainous terrain.
Other stuff: I am interested in nuclear nonproliferation and disarmament. Here is a great podcast about these topics.
