Research interests
His research focuses on applying a multifaceted set of advanced classical molecular dynamics simulation techniques and rare event simulation methods to understand equilibrium and dynamic properties in aqueous and interfacial systems, with the overarching goal of enabling a predictive understanding of the reactive processes that govern ion association and nucleation mechanisms for energy conversion and storage applications, materials engineering at extreme conditions, and geochemically relevant systems.
Subject Matter Expertise
Energy Storage, Enhanced sampling and rare event theories, Large Scale MD, Nucleation, Thermodynamics and kinetics in aqueous solutions and at interfaces, Force field/Machine learning interatomic potential development.
