Hi! I'm Xinyi.
I am a Postdoctoral Scholar in the Paul G. Allen School of Computer Science & Engineering and a Data Science Postdoctoral Fellow in the eScience Institute at the University of Washington. I am fortunate to work with Amy Zhang and Tim Althoff.
My research aims to advance AI, with a current focus on LLMs and RAG, to foster social and technological trust. It leverages multimodal and behavioral data while integrating insights from social sciences to address social challenges—ranging from m/disinformation to well-being—and to build aligned and trustworthy technologies for diverse populations. Check out our recent work as an example; feedback is welcome!
I collaborate with exceptional researchers, practitioners, and students from various disciplines and organizations (e.g., nonprofits). Our work has been published in journals such as ACM Computing Surveys (IF: 23.8) and presented at conferences, including WWW, KDD, WSDM, CIKM, ICWSM, and PAKDD, with 4200+ citations.
I was selected as a Rising Star in EECS and a Rising Star in Data Science in 2024.
