Biography

Dr. Arefiev's research is primarily focused on the study of laser-plasma interactions, relativistic plasmas, and high energy-density phenomena, including applications, through first-principle high-performance computing. Dr. Arefiev has a broad plasma physics background both in analytical theory and simulations in the areas that include plasma propulsion, microwave plasma heating, plasma sources, and basic plasma physics. Dr. Arefiev received his B.S. in physics from Novosibirsk State University (Russia) in 1998 and his Ph.D in physics from The University of Texas at Austin in 2002. In 2003, Dr. Arefiev was selected by the Division of Plasma Physics of the American Physical Society to receive the Marshall N. Rosenbluth Outstanding Doctoral Thesis Award for his work on plasma propulsion. Dr. Arefiev serves as a co-executive secretary of the Joint Institute for Fusion Theory (2011- present).
