David Trebotich is a staff scientist in the Applied Numerical Algorithms Group at Lawrence Berkeley National Laboratory. His research involves end-to-end development of high resolution algorithms for complex flows in multiscale, multiphysics systems using adaptive, finite volume methods. In particular he has implemented this approach in the hpc suite of application codes known as Chombo-Crunch for solving flow and transport in arbitrarily complex geometries. Current applications of interest revolve around solutions to flow and transport equations in complex media–geological (subsurface), engineered (battery electrodes, paper drying felt). Prior to the Berkeley lab, David was staff scientist at the Lawrence Livermore National Laboratory in the Center for Applied Scientific Computing from 2001 to 2009, and before that a post-doc at UC Berkeley after completing his Ph.D. there in 1998.
