About me











The joint topology seminar is returning in fall 2016! We are planning a rotating seminar between Duke, UNC, and NC State; more details to come.

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.
