Research Interests

I am a Project Research Scientist in the Center for Computational Sciences and Engineering (CCSE) in the Computational Research Division of the Computing Sciences Directorate at the Lawrence Berkeley National Laboratory.

I am based in the CCSE Combustion Team and am working actively for the ECP Pele project on the development of the two AMR (Adaptive Mesh Refinement) combustion modeling codes PeleC (compressible) and PeleLM (Low-Mach) designed for exascale computing.
