My general area of research is gravitation and cosmology. Particular topics on which I've worked are: large scale structure in the cosmic microwave and X-ray backgrounds; the integrated Sachs-Wolfe effect and the implied accelerated expansion of the universe; diffuse emissions from clusters of galaxies; infrared and optical searches for dark matter; and both experimental and theoretical studies of gravitational radiation.
