My research goal is to develop science and technology to account for information flows in complex systems, in particular, systems in which security, privacy, and fairness are of central importance. My work has helped develop the research areas of Privacy through Accountability and Compositional Security. Methodologically, my work involves formalizing nuanced concepts (e.g., notions of privacy and transparency) and reasoning that complex programs (e.g., for big data analytics and cryptography) respect these formal properties. I am affiliated with the CMU Security and Privacy Institute and the Principles of Programming group.
