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 encompasses data mining, machine learning, natural language processing, and social computing. It focuses on advancing AI to effectively and responsibly address complex societal problems – misinformation, polarization, healthcare, information and collaboration overload, and more – often requiring leveraging multimodal and behavioral data, being grounded by social science theories, and making sense of techniques’ social implications. I am fortunate to collaborate with exceptional researchers and students; our work has been published in/presented at CSUR, WWW, KDD, WSDM, CIKM, PAKDD, and ICWSM, cited 3800+ times.

Recently, I’ve been particularly passionate about retrieval-augmented and human-centered large language models (LLMs), along with answering: What are approaches to enhance the capabilities of LLMs in generating high-quality responses and making better-informed predictions? How can LLMs support and inspire trust-building conversations around tricky topics? How do we develop LLM agents that align with social norms, collaboration dynamics, and personal preferences? How do LLMs influence people’s information seeking and decision-making? Let’s chat if you are also interested!

Meet Pumpkin, my cat 🤗

I took so many photos of Pumpkin and recently started moving them to Instagram (@pumpkin.not.pumpkout).
