Hello! I’m a postdoc at Harvard University, hosted by Heng Yang. Previously I did my phd at Boston University, under the amazing guidance of Yannis Paschalidis and Ashok Cutkosky. Long ago I did my undergrad at Tsinghua University.

I’m broadly interested in the foundation of data science. Specifically, my research centers around adaptive online learning, which concerns the theory and practice of sequential decision making with Bayesian-type prior knowledge.

On the application side, I’m excited about various aspects of robotics and automation, especially algorithmic approaches that efficiently utilize large-scale pretraining (e.g., continual fine-tuning and conformal prediction).
