McKnight Presidential Professor of Mathematics
School of Mathematics, University of Minnesota

I am a mathematician and an educator. My research mostly concerns numerical analysis, partial differential equations, mechanics, and the interplay between these fields. Much of my recent effort has been directed toward the development of the finite element exterior calculus. In 2009 and 2010 I served as president of SIAM, the largest applied mathematics and computational science professional organization in the world. From 2001 to 2008 I directed the IMA, the world's leading interdisciplinary mathematical research institute.
