About me











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

The Duke mathematics department is starting DOmath, a new collaborative summer research program for Duke undergraduates, in summer 2017. Here are links to information about DOmath and the online application (deadline February 20, 2017). Please feel free to email me if you are interested and have questions.

Solutions to the 2016 Putnam competition are now available.

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.
