I am a cryptography and privacy
researcher.
Currently, I am a member of the
Cryptography, Security, and Privacy lab at the University of
Waterloo.
I am also the Chief Scientist for the Zcash Foundation.
I am currently involved in the NIST standardization effort for
threshold signature schemes; to standardize FROST and Sparkle,
two threshold schemes which I am a co-author of.
Before moving into cryptography research, I worked as an engineer
on open-source security and privacy related projects, including
Tor, Enigmail, and the Off-The-Record (OTR) messaging protocol.
My current and past research includes the following:
