Russ Caflisch, Director

russ caflisch Russ Caflisch studied mathematics at Michigan State and NYU’s Courant Institute of Math Sciences. He began his teaching career at Stanford, then returned to NYU in 1984, before joining the mathematics faculty of UCLA in 1989. More recently, he was a founding member of California NanoSystems Institute (CNSI). Dr. Caflisch served on IPAM’s Board of Trustees for several years and as an organizer of two IPAM long programs before he was recruited to be IPAM’s Director in 2008. He was an Alfred P. Sloan research fellow and an invited lecturer at the 2006 International Congress of Mathematicians, and is a fellow of the American Academy of Arts and Sciences, the American Mathematical Society (AMS), and the Society for Industrial and Applied Mathematics (SIAM). His research interests include materials science, mathematical finance, Monte Carlo methods, kinetic theory, plasma dynamics, fluid dynamics, and PDEs. You can reach Dr. Caflisch by email at rcaflisch@ipam.ucla.edu

Skip Garibaldi, Associate Director

Skip Garibaldi This is Skip Garibaldi's second time at UCLA – the first was as a postdoc in the mathematics department at the start of the millennium. He studied mathematics and computer science at Purdue (BS) and mathematics at UCSD (PhD), was a postdoc at the Swiss Federal Institute of Technology in Zurich, and held visiting positions Université d'Artois, Université Paris-Nord, and IHES in France. He is currently on loan from Emory University, where he is a professor in the department of mathematics & computer science. His research on linear algebraic groups and cohomological invariants in Galois cohomology has been funded by the National Science Foundation and the National Security Agency. Millions of people have seen him explain popular mathematics on television, and he is featured in a museum exhibit about mathematics that is traveling the country. You can read more about him at http://www.garibaldibros.com/ or you can reach him by e-mail at sgaribaldi@ipam.ucla.edu.

Christian Ratsch, Associate Director

christian ratsch

Christian Ratsch grew up in Berlin, Germany, where he received his undergraduate education at the Technical University. He moved to the United States in 1988, where he completed his Ph.D. in physics at Georgia Tech in 1994. He went on to gain a short appointment at the Imperial College in London, and then a 2 year post-doc at the Fritz-Haber-Institut in Berlin. Christian Ratsch came to the UCLA math department in the summer of 1997. He has been at UCLA since then, and he joined IPAM as the Associate Director in the summer of 2006.

Christian Ratsch's research interests are mathematical and physical modeling and simulation of problems in materials sciences on all appropriate time and length scales. His expertise includes density-functional theory (DFT), stochastic, atomistic models (KMC), and continuum type models (level-sets). The research topics of his research group include modeling and simulation of growth of thin films and nanostructures, design and optimization of new hybrid solar cells, and design and optimization of new heterocrystals.

In his spare time, Christian takes full advantage of the Southern California climate. He enjoys running, swimming, cycling, climbing as well as competing in marathons and triathlons. Christian Ratsch's personal homepage is at www.math.ucla.edu/~cratsch. He can be reached by email at cratsch@ipam.ucla.edu.

Stan Osher, Director of Special Projects

stanley osher Stan Osher grew up in Brooklyn, New York and got his MS and PhD (1966) from the Courant Institute, NYU. After working at Brookhaven National Laboratory, UC Berkeley, and SUNY, Stony Brook, he arrived at UCLA in 1976 as a visiting Professor. He has been here since then. Dr. Osher works in i) level set methods for computing moving fronts involving topological changes, ii) the development of methods for approximating hyperbolic conservation laws and Hamilton-Jacobi equations, iii) total variation and other partial differential equations based image processing techniques and in scientific computing and applied partial differential equations. He has been a Fulbright and Alfred P. Sloan Fellow, received the NASA Public Service Group Achievement Award, and was an invited speaker at the International Congress of Mathematicians (1994). His work has been written up numerous times in the scientific and international media, e.g., Science News, Die Zeit (both in 1999). Stan Osher can be reached by email at sosher@ipam.ucla.edu
