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. ## Contact Information:The Australian National University, Mathematical Sciences Institute, John Dedman Building, Canberra, 2601, AustraliaEmail: p.wedrich(at)gmail(dot)com |
