I am an Assistant Professor in the Department of Mathematics. I got my degree from this department in 1993 and my Ph.D. from MIT in 1999. I was a postdoc at Centre de Recerca Matemàtica during the academic year 2000/2001 on a fellowship from FCT . I spent some time at the University of Chicago and the Hebrew University of Jerusalem .
