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 (ML) 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). A recurring theme of my research is about the relationships between ML and people. Some “buzzwords” that my existing research is relevant to include graph ML, trustworthy ML, multi-task learning, and recommender systems. I’m also dipping into explainable ML and NLP.

Pronunciation of my first name: Jia-Chi.

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