I am an Associate 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 August 2018).

Caitlin Leverson, Tye Lidman, and I co-organized the Southeastern Undergraduate Mathematics Workshop (aimed at undergraduate math majors) at Georgia Tech, August 7-11, 2017. This workshop will be held again in Summer 2019. Stay tuned for more information.

Allison Moore and I are co-leading a project on Heegaard Floer homology and low-dimensional topology as part of the Women in Symplectic and Contact Geometry and Topology workshop at ICERM, July 22-26, 2019. The deadline for applications is December 3, 2018.

## Research

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.

In Summer 2017, Robert Lipshitz, Danny Ruberman, and I co-organized a workshop in Oaxaca, Mexico, which included a discussion of open problems. A list of these problems is included in the final report, available here.
