About me











I am a co-director for DOmath, the Duke math department's collaborative summer research program for Duke undergraduates. The 2018 program ran from May 29 to July 20; here is a link to information about DOmath 2018.

I help to organize the Triangle Topology Seminar, a joint seminar between Duke, NCSU, and UNC. Here is a link to upcoming seminars.

Solutions to the 2017 Putnam competition are now available.

I am an editor for the journal Quantum Topology. Please send me a message if you are interested in submitting an article, especially in symplectic and contact topology.
