I work on interdisciplinary study of AI and Social Science. On one hand, I investigate the societal impact of AI, including education, equality, policy, and more. On the other hand, I develop responsible AI and related techniques that mitigates negative societal consequences, prioritizing aspects such as safety, reliability, and privacy. My long-term goal is to comprehend and improve the relationship between AI and society.

Topics I currently focus on:
