semantics), probability theory,
distributed systems, game theory, and AI, and I like to think that it contributes
to our understanding of each of these areas as well.
Some themes of my current research
include: (1) applying ideas of decision theory to constructing algorithms
in asynchronous distributed systems, database systems, and wireless systems;
(2) providing foundations for useful qualitative notions of decision theory;
(3) reasoning about security.
