Affiliation

I am a postdoctoral researcher in Center for Computational Sciences and Engineering (CCSE) in the Computing Sciences Area at the Lawrence Berkeley National Laboratory.

Research Interests and Previous Research

My research interests include mathematical modeling of physics processes, numerical algorithms for complex PDE systems, and high performance computing. During my PhD research, I worked on development and implementation of numerical algorithms in the parallel, relativistic, 3D electromagnetic Particle-in-Cell code called SPACE. We used SPACE code for modeling and simulation of laser-plasma interactions and wakefield acceleration experiments at the Accelerator Test Facility of Brookhaven National Laboratory. During my one-year postdoc at Stanford University, I worked on modeling laser-particle coupled beam propgation for space propulsion systems and kinetic modeling of low temperature magnetized plasmas to study microturbulence in various plasma discharges and anomalous transport in Hall thrusters.

Current Research

I am currently working with the ARTEMIS and WarpX teams. Details to follow...
