About me

Our solutions to the 2015 Putnam competition are now available.

I am on sabbatical during the 2015-2016 academic year, partially funded by the Simons Foundation's Simons Fellows program. I will be based at Duke but will spend extended periods in Sweden and Princeton; please see my Travel schedule page for more information.

In Fall 2015, I am an organizer for the program “Symplectic Geometry and Topology” at the Institut Mittag-Leffler in Sweden.

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.

In recent years, a panel of people at Duke, including me, have held Math Jam chats, hosted by Art of Problem Solving, to discuss Duke's undergraduate program (especially in math) with prospective students. Here are transcripts from our past chats: November 2013; October 2012; October 2011; November 2010.
