My current research interests lie in the interactions between algebraic geometry and number theory. Currently, I'm working on four broad projects. One deals with understanding a geometric analog of the classical theory of epsilon factors. Another (joint w/ M. Strauch and T. Schmidt) project deals with a geometric localization of codamissible modules arising in p-adic representation theory. This will eventually be applied to understanding certain locally analytic representations of central interest to the p-adic Langlands program. In joint work w/ M. Nori, we study the structure and periods of various motives arising from higher homotopy theory. Finally, in joint work w/ G.V. Ravindra, we invesitgate motivic versions of the classical weak Lefschetz theorem.
