About Me

I am currently a Postdoctoral Fellow at Harvard University working with Prof. Hima Lakkaraju. In Fall 2023, I will start as an Assistant Professor at School of Information Sciences, University of Illinois Urbana-Champaign. I received my Ph.D. from University of Michigan and B.Eng. from Tsinghua University.

I’m generally interested in understanding and improving machine learning for complex real-world data (e.g., graphs, rankings, partially observed data), under different contexts (e.g., distribution shift), in terms of various metrics (e.g., accuracy, efficiency, robustness, fairness). I’m particularly interested in research problems motivated by human-related applications. Some “buzzwords” that my existing research is relevant to include graph machine learning, trustworthy machine learning, multi-task learning, and recommender systems.

Please check my Google Scholar and Github. Contact: Email and Twitter.

Pronunciation of my first name: Jia-Chi.

I have openings for Ph.D. students starting in Fall 2023. Please see here for more details.
