I received a Bachelor of Science degree from the University of Michigan and the Ph.D. degree from Yale University. In addition to having been a faculty member at the University for 25 years, I have held research and visiting positions at Penn State University, UCLA, Princeton University, the University of Geneva, and the Eigenössiche Technische Hochschule, Zurich.

My research interests in mathematical physics include quantum mechanics (Schrödinger operators, semi-classical and high-energy limit problems) and statistical physics (classical and quantum lattice spin systems). Most recently I have been working in non-equilibrium statistical mechanics.
