Dr. Ballantyne obtained his Ph.D. in 2002 from the University of Cambridge. He then held postdoctoral fellowships at the Canadian Institute for Theoretical Astrophysics and the University of Arizona. In 2008, he was one of the four founding faculty members of the Center for Relativistic Astrophysics in the School of Physics at Georgia Tech. He is presently an Associate Professor and the Associate Chair for Graduate Studies in the School of Physics.
His research concentrates on topics in high-energy astrophysics, with an emphasis on interpreting existing data and making predictions for future observations. His main interests are the evolution of galaxies and their central supermassive black holes, and the physics of accretion disks around both black holes and neutron stars. His work often involves comparing computer based models with published data from X-ray, radio and/or infrared telescopes.
