I received my PhD in 2010 under the supervision of John Terilla at the Graduate Center of the City University of New York (alternate site).
From 2010 to 2013 I worked as an NSF postdoc at Northwestern University.
From 2013 to 2019 I worked as a research fellow at the IBS Center for Geometry and Physics in Pohang, South Korea.

This is an atlas of Betti numbers of unordered configuration spaces of small graphs.
I compile and maintain notes in LaTeX of many conferences, seminars, workshops, and courses.Here are notes for some talks I've given.
