Research Interests: Multi-wavelength (primarily X-ray) spectroscopic studies of energetic accretion systems (X-ray binaries, AGN). Interstellar dust studies (composition and distribution) through laboratory experiments and space-based observations.
Robert Treat Paine Professor of Practical Astronomy
Research Interests: Compact objects and binaries in globular clusters and the origin and evolution of compact X-ray binaries. Accretion onto white dwarfs, neutron stars, and black holes. Development of a balloon-borne hard X-ray-imaging telescope and future space missions for hard X-ray observations of X-ray binaries and quasars.
