Research

I received my undergraduate degree from the University of Oklahoma in 2002, where I wrote an undergraduate thesis on Numerical Semigroups with Professor Andy Miller. However, when I came to Berkeley in the Fall of 2002, I had developed an interest in studying Analysis and PDE's after doing a good deal of work in physics as an undergrad. There, I finished my Ph.D. working with Professor Daniel Tataru. My thesis topic was the asymptotic behavior of solutions to the Nonlinear Schrodinger Equation (NLSE). As of 2007, I will be at Columbia University as a National Science Foundation Postdoctoral Research Fellow working with Professor Michael Weinstein. However, I will spend the academic year 2008-2009 visiting Professor Herbert Koch at the University of Bonn.
