# Robert V. Kohn

Robert V. Kohn received his Ph.D. in mathematics from Princeton University in 1979, then held an NSF Mathematical Sciences Postdoctoral Fellowship for two years. He has been on the faculty of the Courant Institute of Mathematical Sciences since 1981, with the rank of Professor of Mathematics since 1988. A SIAM Fellow since 2009, his research has addressed many problems at the interface between mathematics and materials science, including coarsening, crystal growth, martensitic phase transformation, micromagnetics, and transformation optics.

Thermodynamic arguments and a one-dimensional model help explain why the grain boundaries in an annealed polycrystalline material have an unexpectedly simple statistical distribution.
