In addition to serving as the deputy, Brissenden also is, and will continue to be, the manager of the Chandra X-ray Center, responsible for the operating one of NASA’s “great observatories” that enables scientists from around the world to obtain X-ray images to reveal the structure and evolution of the universe.

Brissenden is an associate of the Harvard College Observatory and a member of the American Astronomical Society. He has published more than 100 papers and articles in scientific and technical journals and his science interests focus on the broad-band spectral energy distributions of extra-galactic X-ray sources. Brissenden earned a BSc (First Class Honors) in Physics from the University of Adelaide (1985) and a doctorate in astronomy from the Australian National University (1990).
