Alex is a fourth year PhD candidate in computer science at Caltech under the supervision of Thomas Vidick. He is affiliated with the Department of Computing and Mathematical Sciences and the Institute for Quantum Information and Matter.

His research lies at the intersection of quantum computation and cryptography. He is mainly interested in designing new applications for quantum computers, including near-term quantum algorithms and novel cryptographic protocols using lattice-based cryptography. Recently, he has been especially interested in quantum proofs of deletion, privacy-preserving cloud applications and the right to be forgotten. In particular, how can we certify that sensitive user data has been deleted from a remote and untrusted server?
