Self-consistent GW and vertex corrections
Studying how vertex terms and screening choices shape charged excitations, without inheriting bias from a fixed starting point.
About
My work connects the formal language of many-body theory with robust numerical methods—turning challenging electronic-structure problems into calculations we can test, understand, and build upon.
I am a Ph.D. candidate in theoretical and computational chemistry at the University of Michigan. My research centers on finite-temperature Green’s-function methods for molecules and solids, with a particular interest in fully self-consistent GW and vertex-corrected approaches.
The physics is only half the challenge. I also care about the algorithms and software that make these methods usable: efficient tensor representations, thoughtful approximations, reproducible implementations, and clear numerical validation.
I have taught chemistry as a graduate student instructor and presented my work at meetings including the Midwest Theoretical Chemistry Conference and the Telluride School on Theoretical Chemistry. This site is an extension of that work—a place to turn technical ideas into useful explanations.
I grew up across languages and cultures and work in Mongolian, Chinese, and English, with elementary Japanese. Long before graduate school, I helped lead the student team behind a 1,167.44 m² Guinness World Record origami mosaic in Ulaanbaatar—an early lesson in what careful planning and collective effort can build.
