About me

Applications for DOmath 2018, the Duke math department's collaborative summer research program for Duke undergraduates, are now open. Here are links to information about DOmath 2018 and the online application (the deadline is February 15). Please feel free to email me if you are interested and have questions.

I am a co-organizer for the fourth Duke Mathematical Journal Conference, to be held at Duke in April 2018. If you are planning to attend, please register!

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.
