After three years as a postdoctoral fellow at Princeton University, he joined the faculty of the Department of Mathematics at the University of Pennsylvania, where he currently holds the Thomas A. Scott Chair in Mathematics. He has worked in spectral theory, hyperbolic geometry, univalent function theory, microlocal analysis, several complex variables and index theory. For more than a decade, he has also worked on a range of problems in medical imaging, image analysis, computational electromagnetics and mathematical aspects of population genetics. He was a Sloan Foundation Fellow in 1988–90. In 2007, he founded the Graduate Group in Applied Mathematics and Computational Science at the University of Pennsylvania, which he continues to chair.
