I am an associate professor of mathematics at University of Washington. In my mathematics research, I use the Birch and Swinnerton-Dyer conjecture as motivation to understand the constellation of arithmetic invariants associated to optimal quotients of J0(N). I also use do explicit computations on modular abelian varieties, and am the main author and director of the SAGE project. For more, please see my papers.
From August 2005 to April 2006 I was a tenured associate professor of mathematica at UC San Diego. The weather was beautiful there and I loved it, but I left to Seattle because my wife is a graduate student there.
From 2001 to 2005, I was a Benjamin Peirce Assistant Professor of Mathematics at Harvard University. From May 2000 until May 2001 I was an NSF Postdoctoral Fellow at Harvard, during which time I traveled a huge amount. In May 2000 I received a Ph.D. in mathematics from UC Berkeley (my Ph.D. genealogy tree). My thesis involved the Birch and Swinnerton-Dyer conjecture for modular abelian varieties.
