Hello! I am an EECS Ph.D. student at the University of Michigan in the DeepThink Lab, advised by Qing Qu and working closely with Ismail Alkhouri at Los Alamos National Laboratory. I am thankful to be supported by the NSF GRFP.

My research is on diffusion models, with an emphasis on designing new methods for PDE problems arising in science and engineering: data assimilation, inverse problems, free boundary problems, etc.

Before that, I studied math and CS at UW-Madison, working with Grigorios Chrysos on trustworthy ML. I also worked with Yeyu Wang and the Epistemic Analytics lab on learning analytics.
