I am an Assistant Professor at Georgia Tech. Previously, I was a Ritt Assistant Professor at Columbia University and a member of the IAS.

More details can be found in my CV (last updated 5/17).

Caitlin Leverson, Tye Lidman, and I are co-organizing the Southeastern Undergraduate Mathematics Workshop (aimed at undergraduate math majors) at Georgia Tech, August 7-11, 2017.


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.
