I'm currently a Ritt Assistant Professor at Columbia University. I graduated in 2011 with a PhD in mathematics from the University of Pennsylvania under the supervision of Paul Melvin at Bryn Mawr College. During the 2009-2010 academic year, I was a program associate at MSRI and an exchange scholar at UC Berkeley. During Spring 2013, I split my time between Columbia and the Simons Center.

Here is my CV.


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.
