## Research

I work around low-dimensional topology, which has to do with the properties of shapes we can (nearly) visualize, and usually with some influence from combinatorics, which has to do with the properties of discrete structures, like networks.

My papers on the arXiv. Eventually, I intend to include links to their available published versions, and in the meantime you can consult my CV to see where to find them.

I wrote a survey article on Heegaard Floer homology for the Notices of the American Mathematical Society (January 2021).

A popular article in Quanta magazine describes my joint work with Andrew Lobb on the rectangular peg problem (June 2020).

I am an editor at the (semi-new) journal Studia Scientiarum Mathematicarum Hungarica: Combinatorics, Geometry and Topology. Consider it for your "original research paper of high quality and significance specialized in combinatorics, and combinatorial aspects of geometry and topology!"

## Seminars

The Boston Graduate Topology Seminar

This google calendar reports what is happening in topology seminars across the Boston area.

## Summer School and Book

I organized a graduate summer school entitled "Perspectives on Dehn Surgery'' at ICERM during the dates of July 15-19, 2019. The link will take you to video and other materials from the event, and a book based on the lecture series is in the works.
