معرفی
Dr. Gabriel Kaptchuk is an Assistant Professor in the Computer Science Department at the University of Maryland, College Park (UMD), affiliated with UMIACS and MC2. He focuses on applied cryptography, privacy, and interdisciplinary work at the intersection of computer science and law. Previously, he was research faculty at Boston University and earned his Ph.D. from Johns Hopkins University under advisors Avi Rubin and Matt Green. His research includes secure multiparty computation (MPC), zero-knowledge proofs, steganography, and human-centered cryptography. He emphasizes ethical and societal implications of cryptographic systems and collaborates across disciplines to address privacy challenges in real-world contexts.
Education: Ph.D., M.S., and B.S. in Computer Science from Johns Hopkins University (2015–2020).
Research Interests: Applied cryptography, privacy-preserving technologies, secure multiparty computation, steganography, usable security, and cybersecurity policy. His work bridges technical and social aspects of cryptography, advocating for systems that account for power dynamics and societal impacts. Recent projects include frameworks for harm-aware data release, secure steganography in diffusion models, and privacy-focused research agendas for marginalized communities like sex workers.
Teaching: Taught courses on network security, law and algorithms, and algorithmic governance at UMD and Boston University. Recent courses include INST878D/CMSC839C: Governing Algorithms and Algorithmic Governance and DS457/DS657/JD673: Law and Algorithms.
Grants & Awards: Notably, his work on user expectations in differential privacy received a Best Paper Runner-up at ACM CCS 2021. He actively engages in policy discussions, including responses to NIST guidelines and technical research agendas for digital intimacy and smart home security.
Labs/Teams: Leads research groups exploring MPC for social good, steganography, and privacy-preserving technologies. Collaborates with interdisciplinary teams in policy, law, and ethics to ensure technical solutions align with societal values.
