Assistant professor at CyLab, Carnegie Mellon University's Security and Privacy Institute
Jointly appointed between Software and Societal Systems (School of Computer Science) and Engineering and Public Policy (College of Engineering)
Research focuses on the intersection of cryptography, privacy, policy, law, and societal issues
Aims to explore what one *should* do beyond what one *can* do, and to systematically tailor cryptographic protocols to specific use cases
Interdisciplinary work includes policy and technical analysis of end-to-end encrypted content moderation, compelled decryption, and privacy-preserving computation in contexts like journalism and age verification
Also conducts 'pure' applied cryptography research, including zero-knowledge proofs, multi-party computation, private set intersection, and hash combiners
