About Me
I am an assistant professor in Computer Science, Data Science Institute, and Cognitive Science (affiliated) at the University of Chicago. Previously, I was a postdoctoral researcher in the Computational Social Science group at Microsoft Research. I received my Ph.D. in Computer Science from Stanford University, where I was fortunate to be advised by Percy Liang. Before that, I was an undergraduate at Korea University. My research is at the intersection of human-computer interaction (HCI) and natural language processing (NLP).
My research focuses on Writing with AI, exploring how AI is changing our writing process, the content we create, and our identities as writers. I design and evaluate AI writing assistants (e.g., design space), investigate human-AI collaborative writing processes (e.g., CoAuthor) and conduct user studies, controlled experiments, and surveys to examine the broader implications, such as how AI might shift social norms around authorship, reshape writing education, and influence our everyday communication. I collaborate with researchers across HCI, NLP, and social computing, as well as in fields like education, law, and media.
