John B. Bell

from Wikipedia, the free encyclopedia

John B. Bell (* 1954 ) is an American applied mathematician .

Bell studied mathematics at the Massachusetts Institute of Technology with a bachelor's degree in 1975 and at Cornell University with a master's degree in 1977 and a doctorate under Lawrence Payne in 1979 ( The Noncharacteristic Cauchy Problem for Time Dependent Equations ). He was then a scientist at the Naval Surface Weapons Center and from 1982 to 1986 at Exxon Production Research. From 1986 to 1996 he was at the Lawrence Livermore National Laboratory , of which he became a permanent member in 1988 and headed the Center for Computational Sciences and Engineering from 1993 to 1996, and then at the Lawrence Berkeley National Laboratory (LBNL), where he was head of the department from 2011 to 2014 Mathematics and Computational Science and has been Chief Scientist of the Computational Research department since 2014.

Bell dealt with finite difference methods, numerical hydrodynamics and aerodynamics (for example flow at small Mach numbers), adaptive grid refinement, tracking of interfaces and parallel computing and applications in shock wave physics, combustion, seismology, flow in porous media and astrophysics (supernova) .

In 2005 he received the Sidney Fernbach Award . In 2018 he received the Berkeley Lab's Lifetime Achievement Award. In 2012 he became a member of the National Academy of Sciences . He is a fellow of SIAM and received the SIAM / ACM Prize for Computational Science and Engineering in 2003.

He is one of the founders and editors of Communications in Applied Mathematics and Computational Science (CAMCOS).
