AboutI came to Stanford as a postdoctoral fellow in the fall of 2007. My mentors here are Gunnar Carlsson and Persi Diaconis. Before that I was a graduate student at the University of Washington. My thesis advisors there were Eric Babson and Chris Hoffman. I am also affiliated with Stanford's TMSCSCS group. Some expository mathematical writings can be found on my blog.Potential employers are invited to view my cv, research statement, and teaching statement. Letters of recommendation will soon be available from Eric Babson, Gunnar Carlsson, Persi Diaconis, Chris Hoffman, and Shmuel Weinberger (research), and Ravi Vakil (teaching). Teaching and seminarsIn Fall 2009 I am running the Polya problem solving seminar. Together with Persi Diaconis, I am co-organizing a seminar on "graph homomorphisms". In Summer 2009, I taught MATH 53 (ODE's with linear algebra). In Spring 2009 I taught MATH 108 (Combinatorics) and MATH 161 (Set Theory).ResearchI am broadly interested in interactions of probability and statistical physics with topology, geometry, and combinatorics. Some of my work has applications to the emerging field of topological data analysis. My recent papers are available on the arXiv.
