Research Insterests
My research focuses on clusters of galaxies, the largest collapsed objects in the Universe, using X-ray space telescopes (Chandra, XMM-Newton, Suzaku). I am best known for providing observational constraints on the microphysical properties of the intracluster medium and connecting it with the large scale evolution of galaxy clusters. I also study AGN feedback at centers of clusters and early-type galaxies using X-ray, radio, and EUV observations. I am interested in using machine learning techniques to extract information in the observational data that is inaccessible by conventional methods. My research has been supported by NSF, NASA, and SAO.
