About me











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

Solutions to the 2017 Putnam competition are now available.

My office has changed to Physics 216 (just down the hall from my old office). The office phone number remains the same.

The joint topology seminar has returned! Here is the web page for the seminar: Triangle Topology Seminar.

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.
