Additional Information:

Russel Caflisch received his PhD in Mathematics from the Courant Institute of Mathematical Sciences at New York University in 1978. After a year-long postdoc position at Courant, he was an Assistant Professor at Stanford, before heading back to Courant. At Courant, he received tenure in 1984 and was promoted to Professor in 1988. He moved to LA in 1989 to work at UCLA. Before he worked in nanoscale systems, Russel worked on a wide range of topics in applied mathematics, including kinetic theory of rarefied gas dynamics, multiphase fluid flows, vortical flows, singularity theory for fluid flows and PDEs, quasi-Monte Carlo methods, and computational finance. Currently, he leads a group of applied mathematicians and materials physicists working on modeling and simulation for epitaxial growth and device properties. Multi-scale analysis, combining models and simulation methods at different length scales from the atomistic to the continuum, is a hallmark of this group's efforts. Much of this work is in collaboration with HRL Laboratories in Malibu. Russel was awarded a Hertz Foundation Graduate Fellowship and a Sloan Foundation Research Fellowship.
