New Research Exposition Talks Teaching
I am a Benjamin Peirce and NSF postdoctoral fellow at Harvard University working on various topics in category theory related to homotopy theory. In 2011, I completed my PhD at the University of Chicago under the direction of Peter May. As a graduate student, I began work with Dominic Verity at Macquarie University in Sydney. I am a host of the n-Category Café and occasional contributor to the nLab, a category-theory wiki. I spent the spring of 2014 at MSRI as a member of the program on Algebraic Topology and will be spending time during the summer of 2015 at the Hausdorff Institute of Mathematics as a participant in the Homotopy theory, manifolds, and field theories program. In the fall of 2015, I will be joining the department of mathematics at Johns Hopkins University. Here is my CV.
