I am a postdoctoral scholar in the microelectronics team at the Center for Computational Sciences and Engineering (CCSE) at the Lawrence Berkeley National Laboratory. As a part of the Microelectronics effort, I lead the development of an exascale electrostatic-quantum transport solver, ELEQTRONeX, for modeling electron/phonon transport through nanomaterials. Leveraging the nonequilibrium Green's function method and HPC, the code enables analysis of charge transport within intricate 3D structures. Additionally, I've contributed to electrodynamic modeling of microelectronic circuits using the ARTEMIS Maxwell solver.

I earned my M.S. and Ph.D. in the Aerospace Engineering from the University of Illinois Urbana-Champaign in May 2022. During PhD, I worked on modeling hypersonic flows and led the development of a massively scalable software for solving the Boltzmann Transport equation, using the Direct Simulation Monte Carlo (DSMC) method. Using this tool, I studied challenging problems at the intersection of statistical mechanics, hypersonics, and linear stability analysis, such as modeling 3D shock-wave/boundary-layer interactions.

More information about my background and projects can be found at my webpage.
