Research
I work on interdisciplinary study of AI and Social Science, including AI's societal impact, socially responsible AI (AI safety, security, and privacy), and computational social science. My long-term goal is to understand and advance the relationship between AI and society, exploring both its technological and societal dimensions.
Topics I currently focus on:
