Saurabh S. Sawant

I am a postdoctoral scholar in the Center for Computational Sciences and Engineering (CCSE) in the Applied Math & Computational Research Division at the Lawrence Berkeley National Lab (LBNL) since January 2022.

At LBNL, I am developing exascale electrostatic - quantum transport solver for modeling next-generation nanoscale field effect transistors. I also contribute to the development of software stack for applications in microelectronics and quantum circuits.


I earned my Ph.D. in the Aerospace Engineering from the University of Illinois Urbana-Champaign (UIUC) with a strong focus on high-performance computing.

During Ph.D., I developed massively scalable software for solving the Boltzmann Transport equation using the Direct Simulation Monte Carlo method for studying instabilities in hypersonic flows. I also developed scalable software for implementing data-driven methods such as proper orthogonal and dynamic mode decomposition, and solving eigenvalue problems arising from the linear stability analysis.

2023 Highlights

June 2023: We recently presented our on-going code development for an exascale Electrostatic-Quantum Transport framework in the International Workshop on Computational Nanotechnology (IWCN) 2023 (
