I am on sabbatical leave during the 2016-2017 academic year. I am being partially supported by the Career Enhancement Fellowship from the Woodrow Wilson Foundation.
I do research in algebraic topology. I am particularly interested in higher category theory and its connections with higher K-theory. In 2010, I got my PhD at MIT with Mark Behrens. From 2010 to 2013, I was a postdoc at the University of Chicago working with Peter May.
