David Cash is interested in applied and theoretical cryptography, including provable security for practice and theoretical foundations. He has worked on several topics in symmetric-key and public-key cryptography, including searchable encryption, database encryption, disk encryption, lattice-based (post-quantum) cryptography and homomorphic encryption. More broadly, he is interested in computer security and theoretical computer science.
Assoc. Prof. Cash regularly publishes at flagship cryptography conferences like CRYPTO and EUROCRYPT and flagship computer security conferences like ACM CCS and IEEE Security & Privacy. His work twice won the Best Paper Award at EUROCRYPT. He was the recipient of a National Science Foundation CAREER Award and was named a research fellow at the Simons Institute for the Theory of Computing at the University of California, Berkeley.
