I am an Astrophysicist in the High Energy Astrophysics Division and a member of the Chandra X-Ray Center (CXC). I mainly study the X-ray and multiwavelength emission from galaxies and quasars. My work includes a substantial effort aimed both at teaching and disseminating the Chandra data analysis system to the worldwide astronomical community and at supporting all astronomers using the Chandra X-ray Observatory.
