Researcher Summary

My research interests include applied cryptography, information security and network security. In particular, my work focuses on the design of cryptographic primitives and the proof of their security, applied to the Internet of Things. I have also been working on distributed ledger technologies (blockchains), electronic health systems and electronic voting systems.

Theme leader for UC Biosecurity Innovations.
