Sarah Scheffler is an Assistant Professor at Carnegie Mellon University, jointly appointed between the School of Computer Science and the College of Engineering. She holds roles in the departments of Software and Societal Systems and Engineering and Public Policy, focusing on applied cryptography and its intersections with policy, law, and societal impact.
Her research explores end-to-end encryption, privacy-preserving technologies, and their regulatory challenges, including content moderation, compelled decryption, and autonomous systems. Scheffler earned her Ph.D. in 2021 from Boston University under Mayank Varia, with postdoctoral roles at MIT and Princeton. She advises students in EPP and S3 programs and actively engages in interdisciplinary projects addressing privacy and cybersecurity.
Her work emphasizes cryptographic protocols tailored to real-world use cases, such as zero-knowledge proofs, multi-party computation, and privacy engineering. Scheffler frequently contributes to policy discussions on encryption, data protection, and the societal implications of technology. She is a core member of CyLab, CMU's Security and Privacy Institute.
Publications highlight advancements in secure computation, privacy-preserving algorithms, and legal-technical analyses. Current research includes privacy in age verification systems and scalable content moderation under encryption. She advocates for robust encryption standards despite regulatory pressures, as seen in her CNN commentary on Apple's UK data protection policies.
