Faculty: Department Head, Professor

Biography

Grigory Rogachev is specializing in low energy experimental nuclear physics and nuclear astrophysics. He is doing research related to structure of light and medium mass nuclei, in particular structure of exotic neutron-rich and neutron-deficient isotopes, clustering phenomena in nuclei, mechanisms of nuclear reactions, applications of nuclear physics methods for determining rates of nuclear reactions that drive nucleosynthesis and energy generation in stellar environment. Grigory Rogachev graduated from Moscow Engineering Physics Institute (State University) in 1996 with Master of Science degree in Experimental Nuclear Physics. From 1996 to 1999 Grigory Rogachev was a Research Assistant at the National Research Center "Kurchatov Institute" where he received his Ph.D. degree in 1999. From 2000 to 2004 he was associated with the University of Notre Dame, first as a Ph.D. Research Associateand later as a Research Assistant Professor (2003-2004). In summer of 2004 Grigory Rogachev joined Department of Physics at Florida State University as an Assistant Professor. In 2010 he was tenured and promoted to an Associate Professor. In summer of 2013 he joined faculty at the Department of Physics and Astronomy and Cyclotron Institute at Texas A&M University.
