Oscar Antepara

Oscar Antepara
Postdoctoral Scholar

I am a CSE in the Performance and Algorithms Research (PAR) Group in the Computing Sciences Directorate at the Lawrence Berkeley National Laboratory.

My expertise lies in the development, implementation, and analysis of numerical methods related to computational fluid dynamics using high-performance computing (HPC) systems. Before joining PAR, I was a postdoctoral scholar in CCSE at LBNL where I was working on MFIX-Exa, a new CFD-DEM code developed by the National Energy Technology Laboratory and Lawrence Berkeley National Laboratory as part of the U.S. Department of Energy's Exascale Computing Project, then a postdoctoral scholar in ANAG.

I got my Ph.D. in Engineering from the Technical University of Catalonia-BarcelonaTech (UPC) in 2019, where my research focused on developing adaptive mesh refinement algorithms for turbulent and multiphase flows.
