boards and co-organized the U.S.-based SIAM meetings in computational combustion since 1991. His current primary research interests lie in the areas of computational combustion, energetic materials, chemical vapor deposition, and the numerical solution of ordinary and partial differential equations.

John B. Bell is senior staff mathematician and group leader for the Center for Computational Sciences and Engineering at the Lawrence Berkeley National Laboratory (LBNL). Prior to joining LBNL, he held positions at the Lawrence Livermore National Laboratory, Exxon Production Research, and the Naval Surface Weapons Center. Dr. Bell’s research focuses on the development and analysis of numerical methods for partial differential equations arising in science and engineering. He has made contributions in the areas of finite difference methods, numerical methods for low-Mach-number flows, adaptive mesh refinement, interface tracking, and parallel computing. He has also worked on the application of these numerical methods to problems from a broad range of fields, including combustion, shock physics, seismology, flow in porous media, and astrophysics. He was the recipient of the SIAM/Association for Computing Machinery (ACM) Prize in Computational Science and Engineering in 2003, and he received the Sidney Fernback Award in 2005.

Jacqueline H. Chen is a distinguished member of the technical staff at the Combustion Research Facility at the Sandia National Laboratories. She has contributed broadly to research in petascale direct numerical simulations (DNSs) of turbulent combustion focusing on fundamental turbulence-chemistry interactions. These benchmark simulations provide fundamental insight into combustion processes and are used by the combustion-modeling community to develop and validate turbulent combustion models for engineering computational fluid dynamics (CFD) simulations. In collaboration with computer scientists, Dr. Chen and her team have developed algorithms and software for automated combustion work flow, in situ data mining and visualization of petascale simulated combustion data, and reacting-flow DNS software for hybrid architectures. She received the Department of Energy (DOE) Innovative and Novel Computational Impact on Theory and Experiment (INCITE) Award in 2005, 2007, and 2008-2010, and the Asian American Engineer of the Year Award in 2009. She is a member of the DOE Advanced Scientific Computing Research Advisory Committee and Subcommittee on Exascale Computing. She was the co-editor of the Proceedings of the Combustion Institute, Volumes 29 and 30, and a member of the executive committee of the board of directors of the Combustion Institute.
