Associate Professor Scott Morrison
Biography
I'm an ARC Future Fellow and Associate Professor at the Mathematical Sciences Institute of the Australian National University.
My research interests include Khovanov homology, derived topological quantum field theories (TQFTs), and small examples of subfactors and singly generated tensor categories. More details can be found on my research page, or my lists of publications and talks.
From 2009-2012, I was a Miller Fellow at the UC Berkeley mathematics department During 2007-2009, I was a postdoc at Microsoft Station Q, at UC Santa Barbara.
I completed my Ph.D. in March 2007 at the University of California, Berkeley, studying with Vaughan Jones. My thesis received the Herbert Alexander Prize for Outstanding Dissertation in Pure Mathematics. Before Berkeley, I graduated from the University of New South Wales, Australia, with first class honours and the University Medal in pure mathematics.
