I am a fourth-year graduate student at the University of California, Berkeley. (Note that there is another graduate student of the same name here.) My advisor is David Nadler. I'm interested in homotopy theory, quantum field theory, manifold topology, and higher category theory.

Annoying Precision


On December 6th, 2013, I passed my qualifying exam. Here is my syllabus and transcript.

In the summer of 2013 I was an instructor at the Summer Program for Applied Rationality and Cognition.

In the summer of 2012 I was a counselor at the Program in Mathematics for Young Scientists (PROMYS), where I had previously been a student in the summer of 2006.

I graduated from the Massachusetts Institute of Technology (B.Sc. in Mathematics) in February 2012. From September 2010 to April 2011 I also studied abroad at the University of Cambridge (Part II of the Mathematical Tripos) through the Cambridge-MIT Exchange.
