About me











Applications for the 2019 program for DOmath, the Duke math department's collaborative summer research program for Duke undergraduates, are now open! Here is information about DOmath 2019 and the online application.

Solutions to the 2018 Putnam competition are now available.

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

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.
