Summer 2014: Spring 2014: Fall 2013: Spring 2013: Fall 2012:


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.
