Hi! I'm Xinyi.
![avator.jpg](/assets/img/avator.jpg?7d3d906060cc2e8fe800ea5a1184f233)
I’m a Postdoctoral Scholar in the Paul G. Allen School of Computer Science and Engineering, fortunately working with Amy Zhang and Tim Althoff, and a Data Science Postdoctoral Fellow in the eScience Institute at the University of Washington.
My research aims to advance machine intelligence to tackle social challenges (e.g., misinformation, polarization, information overload, health), which often requires leveraging multimodal and behavioral data, drawing on social science insights, and making sense of the social implications of advanced technologies. I am fortunate to collaborate with exceptional researchers and students from various disciplines; our work has been published in CSUR, WWW, WSDM, CIKM, PAKDD, and ICWSM with 3900+ citations.
Recently, I’ve been particularly interested in human-centered and retrieval-augmented LLMs, along with probing: 1) How can we enhance LLMs’ capabilities to generate high-quality responses and make better-informed predictions? 2) How can LLMs assist in building trust under difficult conversations? 3) What is LLMs’ potential harm, especially to marginalized groups? Let’s chat if you are also interested!
