I am a Research Associate at the Department of Mathematics, Imperial College London.
Before coming to Imperial, I was a PhD student at the Department of Pure Mathematics and Mathematical Statistics, University of Cambridge.
I have received my PhD in October 2015.
My advisor is Dr Jacob Rasmussen. In the spring of 2016, I have visited the Max Planck Institute for Mathematics in Bonn, Germany. From October 2017, I will be a Postdoctoral Fellow at the Australian National University's Mathematical Sciences Institute. 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. ## Contact Information:Imperial College London, Department of Mathematics, 6M50 Huxley Building, South Kensington Campus London SW7 2AZ, UKEmail: p.wedrich(at)gmail(dot)com |
