From 2011-2015, I was a Ritt Assistant Professor at Columbia University. Beginning in Fall 2015, I will be an Assistant Professor at Georgia Tech. During the 2015-2016 academic year, I will be on leave at the IAS.

More details can be found in my CV (last updated 8/15).


I study low-dimensional topology, in particular knot theory, concordance and Heegaard Floer homology. My preprints and papers are available on the arXiv.

A talk I gave in August 2012 was blogged about on the Electric Handle Slide, a graduate student blog focusing on symplectic and low-dimensional topology.

In March 2014, Tye Lidman and I co-organized an AMS special session, which included a discussion of open problems. A list of these problems is available here.
