I am an Assistant Professor at the Department of Computer Science of the University of Illinois at Urbana-Champaign (UIUC).
I received my Ph.D. from the University of Washington, with Noah Smith, and my Bachelors Degree from Peking University. I spent one year at the Allen Institute for Artificial Intelligence as a Young Investigator, and time at Microsoft Research, Google, and DeepMind as an intern.
My research interest broadly spans natural language processing and machine learning. My current interests primarily include making language AI more efficient and accessible, and evaluating and improving large language models’ reasoning capabilities, factuality, and trustworthiness, and their applications in the scientific domain.
Outside of work, I cater to the whims of a trio of furry overlords: Meera, Loki, and Sylvie. When they release me from their service, I cycle in the summer, and (backcountry) ski in the winter.
