Marsha Berger came to the Courant Institute of Mathematical Sciences as a postdoctoral fellow, joined the faculty in 1985, and became a full professor in 1993. Drawing heavily on the areas of computer science, numerical analysis, and applied mathematics, her interdisciplinary research deals in scientific computing with an application to fluid dynamics. She works closely with aerodynamicists at NASA. Professor Berger was elected to the prestigious National Academy of Sciences in 2000. Among her many honors are the NASA Software of the Year Award, the NYU Sokol Faculty Award in the Sciences, the NSF Faculty Award for Women, and the NSF Presidential Young Investigator Award. She is currently on the Board of Governors of the Institute of Mathematics and its Applications. Professor Berger earned her B.S. in mathematics at SUNY-Binghamton, and an M.S. in computer systems and a Ph.D. in numerical analysis at Stanford University.
