Dr. Miller joined the MIT Kavli Institute in 2004. He is a member of the Suzaku Science Working Group and Suzaku XIS instrument team, and under a Short-Term Postdoctoral Fellowship by the Japanese Society for the Promotion of Science (JSPS) in 2005-2006, he worked for six months with the Suzaku XIS team at Osaka University in Japan. He is also a member of the Chandra ACIS science team at MKI, and a member of the Science Working Group and software and calibration team for the upcoming Japanese ASTRO-H mission. He is active in instrument calibration as a member of the International Astronomical Consortium for High Energy Calibration (IACHEC).

Dr. Miller studies the structure and evolution of clusters and groups of galaxies, primarily by observing the X-ray emission from diffuse hot gas in these systems. His other research interests include the hot phase of the Galactic interstellar medium; the multi-phase gaseous interface between galaxies and intergalactic space; and radiative processes in the Solar Wind. He has a wide range of data analysis expertise, spanning radio, optical, UV, and X-ray imaging and spectroscopy.
