BIOGRAPHY

I am a PhD student at UC San Diego department of Computer Science and Engineering, advised by Prof. Rose Yu and Prof. Yian Ma. I received my Bachelor degree of science in Applied Math, Physics, and Computer Sciences from the University of Wisconsin-Madison in 2020. My research primarily lies in Uncertainty Quantification, Deep Generative Modeling, Bayesian Deep Learning, and Spatiotemporal Modeling. My works have been applied to forecasting spatiotemporal systems in epidemiology, traffic and climate science.
