Research

Electronic Structure Calculations for Strongly Correlated Electron Systems
Despite their broad and crucial applications, strongly correlated electron systems are well-known for presenting significant challenges when using Kohn-Sham density functional theory with the existing exchange-correlation functional approximations, often resulting in non-negligible systematic errors. My collaborators and I have dedicated our efforts to exploring alternative formulations that more accurately describe electron behavior in these systems, and to developing numerical methods for the associated optimization problems.

Electronic Structure Calculations for Strongly Correlated Electron Systems
Optimization for Atomistic Simulations
Atomistic simulations form the foundation and computational bottleneck in high-throughput materials design, phase diagram calculations, and more. Following molecular statics, my collaborators and I formulate the related optimization problems with physical constraints and develop globally convergent algorithms and reliable packages.
