His research is directed broadly to the problem of reconciling
general relativity with quantum mechanics, and his current efforts
in that direction center on causal set theory, which replaces continuous
spacetime by a collection of discrete "atoms" structured as a
locally finite order.
Beyond science, he takes interest in languages, music, political economy and the outdoors.
