David Brown is Deputy Department Head for Science & Technology in the Computing Applications & Research (CAR) Department. He is responsible for overseeing science and technology (S&T) planning, execution and new initiatives in CAR. He is also the Computation Directorate's LDRD point of contact and principal point of contact for the Office of Advanced Scientific Computing Research in the DOE Office Of Science. Dr. Brown's research expertise and interests lie in the development and analysis of algorithms for the solution of partial differential equations (PDEs). In particular, his research has focused on adaptive composite overlapping grid techniques for solving PDEs in complex moving geometries and in the analysis of difference approximations for PDEs. Before assuming his current position in CAR, he led the highly successful Overture project, which in 2001 was named one of the 100 "most important discoveries in the past 25 years" by the DOE Office of Science. Dr. Brown earned his Ph.D. in Applied Mathematics from the California Institute of Technology in 1982. He also holds a B.S. in Physics and an M.S. in Geophysics from Stanford University. He joined Lawrence Livermore National Laboratory in 1998.
