Katelyn Xiaoying Mei
Ph.D. Candidate
University of Washington
I'm a fourth-year PhD candidate in Information Science at the University of Washington. I'm fortunate to be advised by Lucy Lu Wang and Katharina Reinecke. I'm also very grateful to be mentored by Allison Koenecke and Mona Sloane . Before my PhD, I spent four amazing years at Middlebury College from which I obtained my Bachelor's of Art in Psychology and Mathematics.
My research interests derive from the intersection of psychology, humanties, and data science. Through large-scale online experiments and collection of real-world social media data, my projects focus on human cognition and decision-making in the age of generative AI, including 1) how individuals interact with AI systems in various settings, 2) how AI systems affect individuals' behaviors, and 3) psychological factors underlying our engagement with AI systems.
