I received my Ph.D. from U.C. Berkeley in 2009 under the supervision of Nicolai Reshetikhin. I am currently in the final year of a three year NSF postdoc at Columbia University, where my sponsoring scientist is Dylan Thurston. My research concerns example driven questions in quantum algebra and quantum topology. In particular, I am interested in the classification, topology, and arithmetic of fusion categories and subfactors.
3-dimensional topology and finite tensor categories (with Chris Douglas and Chris Schommer-Pries). Applying the cobordism hypothesis, we generalize the Turaev-Viro TFT in three ways: extending the TFT down to points, getting 3-framed TFTs from non-spherical fusion categories, and getting noncompact 3d TFTs from non-semisimple finite tensor categories. ETA: November 2011.
The Brauer-Picard groupoid of the Asaeda-Haagerup categories (with Pinhas Grossman). We compute the Brauer-Picard groupoid of the Asaeda-Haagerup categories. Like in the Haagerup case there is a new third fusion category Morita equivalent to the other two, but unlike in the Haagerup case the group of Morita autoequivalences is nontrivial. ETA: Fall 2011
Kashaev-Reshetikhin Knot Invariants (with Scott Morrison). We clarify some details of Kashaev-Reshetikhin's construction of invariants of knots together with a flat SL(2) connection and compute these invariants for some small examples. ETA: Spring 2011. (Answers to calculations available by request.)
In the summer of 2002 I taught a tutorial at Harvard on L-functions and zeta functions.
Here are the notes from lectures (in pdf): 1, 2, 3, 4, 5 and 6, 7, 8 and 9, 10
Here are the homeworks (in pdf): 1, 2
Here are the suggested paper topics (in pdf).
In the spring of 2002 I wrote my senior thesis at Harvard under the supervision of Benedict Gross. It was titled "Artin L-Functions: A Historical Approach." It received highest honors from the math department. Here it is in pdf.
In the fall of 2001 I wrote a paper on the distribution of primes in F_p[x] for a seminar taught by Tom Brennan. I received advice on both the content and presentation of this paper from both Tom Brennan and Keith Conrad. Here it is in pdf.
