Hi, I’m Bryant

I’m a Ph.D. candidate in Materials Science and Engineering at UC Berkeley, working with Prof. Kristin Persson at Lawrence Berkeley National Laboratory. I develop machine-learned interatomic potentials to simulate million-atom reactive interfaces in solid-state batteries—work that would take millions of CPU-hours with traditional methods.

My research has uncovered hidden SEI morphologies invisible to experimental characterization, explained passivation mechanisms through electronic structure analysis, and contributed to open-source tools used by 50+ researchers worldwide.
