I am a professor in the
Department of Computer Science at
the University of California, Davis, USA.
I have also been a visiting professor at a bunch of places, including
Chiang Mai University (TH),
Chulalongkorn University (TH),
ENS Paris (FR),
ETH Zürich (CH), and
The Isaac Newton Institute (UK).
My research is in cryptography.
After finishing an undergrad degree from UCB,
I did my Ph.D. at MIT’s
Theory of Computation group (1991),
After that I worked at IBM as a security architect, then came to UCD (1994), where I’ve spent most
of the last 24 years.
My research has focused on obtaining
provably-good solutions to protocol problems of genuine utility.
In recent years, I’ve been lucky enough
to get some nice recognition:
Levchin prize (2016),
IACR Fellow (2012),
Paris Kanellakis Award (2009).
These days, my technical work in cryptography is paired with corresponding concerns for social and ethical issues
connected to technology, especially the problem of
mass surveillance. I’ve been working on
a small book on that topic.
