IPAM carries out its mission with the assistance and support of many people in a variety of roles.  The IPAM community consists of the directorate, staff, Science Advisory Board, Board of Trustees, and of course, program organizers, speakers, and participants, which are unique to each program. You can read about current members of the directorate and staff below.  Openings for associate director will be posted on this site every two or three years; staff openings are advertised on UCLA Campus Human Resources. The Science Advisory Board approves all scientific programs sponsored by IPAM.  The Board of Trustees approves the budget and plans for the upcoming year. Each board meets once a year and communicates with the Director regularly. Members serve four year terms. IPAM's directors are ex-officio members. The building directory includes all directors, staff and participants of the current long program with offices at IPAM.
Dima Shlyakhtenko

Dima Shlyakhtenko

Director

Dimitri (Dima) Shlyakhtenko was appointed Director of IPAM on July 1, 2017. Shlyakhtenko has been a member of the faculty at UCLA department of mathematics since 1998, and served as the department chair from 2012 to 2015. His research is on Operator Algebra and includes free probability theory, random matrix theory, as well as von Neumann algebras and L2-invariants. He received his PhD from University of California, Berkeley in 1997 at the age of 22. He was the recipient of a Sloan Foundation Fellowship in 2001 and a Special Project Award from the Clay Mathematics Institute in 2002. The UCLA department of mathematics presented him with the R. Sorgenfrey Distinguished Teaching Award in 2004.  He gave an invited talk at the International Congress of Mathematicians in Hyderabad, India in 2010.

Maria D’Orsogna

Maria D’Orsogna

Associate Director

Maria D’Orsogna is a professor of mathematics at the California State University, Northridge and an adjunct associate professor in the Biomathematics Department in the Geffen School of Medicine at UCLA.  She received her PhD in Theoretical Physics from UCLA in 2003.  She joined IPAM as Associate Director in 2018.  Prior to her appointment, she visited IPAM numerous times as a core participant to four long programs, a speaker at several workshops, and an academic mentor in RIPS.  Her recent work focuses on mathematical models of cell biology, multi-particle swarming, and social science systems, which she studies using tools from statistical mechanics and applied mathematics. D’Orsogna is the author of more than fifty refereed publications. Her work is supported by the NSF and by the Army Research Office. She is also a passionate environmentalist and has led a successful grassroots movement in Italy to stop oil drilling at sea and in sensitive areas.

Stan Osher

Stan Osher

Director of Special Projects

Stan Osher grew up in Brooklyn, New York and obtained his PhD from the Courant Institute at NYU.  After working at Brookhaven National Laboratory, UC Berkeley, and SUNY Stony Brook, he arrived at UCLA in 1976 as a visiting Professor and never left.  Dr. Osher has co-invented and developed: the level set methods for computing moving fronts involving topological changes; essentially nonosillatory high order methods for approximating hyperbolic conservation laws and Hamilton-Jacobi equations; total variation and other partial differential equation based image processing techniques; fast optimization algorithms for L1 based regularization, and diffusion generated geometric motion. Among his many honors, he has given regular (1994) and plenary (2010) invited addresses at the International Congress of Mathematicians and the John von Neumann lecture at the annual SIAM meeting; he is a fellow of SIAM, the AMS, and the American Academy of Arts and Sciences; and is a member of the National Academy of Sciences.

Christian Ratsch

Christian Ratsch

Deputy Director

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 PhD in physics at Georgia Tech in 1994. After a short appointment at the Imperial College in London and a two-year post-doc at the Fritz-Haber-Institut in Berlin, Ratsch came to the UCLA Mathematics Department in 1997. He has been at UCLA since then, and joined IPAM as the Associate Director in 2006. 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.
