PhD Candidate
Sarah is a Ph.D. student in the BUsec group working with Prof. Mayank Varia.
She is studying applied cryptographer, including zero-knowledge proofs, multi-party computation, secure messaging, private set intersection, and hash combiners. Her applied cryptography research creates new cryptographic capabilities inspired by the needs of society, law, and policy.
Since 2019, she has been the organizer of the BUsec Seminar for security, cryptography, and privacy. She is also an active member of the Cyber Security, Law, and Society Alliance.
Sarah is interested in improving the law’s understanding of technology, and technology’s understanding of the law and society. She believes that the current lack of mutual understanding between these fields is harming society and individuals caught in the crossfire. She hopes to help by gaining and spreading an understanding of both fields. She also has a lot of opinions about machine learning, and how you shouldn’t use it for things that bear high costs to individuals when the predictions are wrong, and at the very least you should be using algorithmic fairness techniques.
