Research

My research interest is applied cryptography in operationally constrained environments. Over time my focus has shifted from integrating cryptographic techniques into larger systems toward the design, implementation, and assessment of cryptographic protocols themselves, particularly fully homomorphic encryption and zero-knowledge proofs under real deployment constraints.
