Working with me
I'm an Assistant Professor in the Information School at the University of Texas at Austin. Previously, I was a visiting researcher on the AI Interaction and Learning team at Microsoft Research and a postdoc working with Yejin Choi at the University of Washington. I received my PhD from Language Technologies Institute at Carnegie Mellon University, advised by Yulia Tsvetkov. For more information, please check my CV.
Research Interests
I build socially intelligent AI systems that adapt to the diversity of human perspectives, values, and needs. My goal is to make AI systems safer, more useful, and more equitable for the people and communities they serve.My research brings together three closely connected directions: LLM post-training and preference learning for personalized AI that reflects individual and community needs; pluralistic alignment that enables models to represent and navigate diverse values; and AI safety for systems that must reason about social context, human values, and interactions.
To advance these goals, I develop training methods, data, and evaluations that incorporate social context into language models. I study where models fail across communities, languages, and cultures, with particular attention to subjective phenomena such as sentiment, affect, and values. I also investigate how these challenges emerge in multi-agent systems, designing methods for safer and more reliable collaboration, communication, and coordination.
