Dr Shprits' primarily area of scientific research is understanding the dynamics of the radiation belts and their effect on satellites. Dr Shprits has developed codes to quantify the dynamical evolution of the radiation belts. He has also developed codes to quantify quasi-liner scattering rates due to wave-particle interactions. He has quantified the effects of scattering by ELF/ VLF and ULF waves and identified a number of critical effects associated with radial diffusion, local acceleration and loss of the radiation belt electrons. His bibliography includes over 70 publications in peer reviewed journals out of which 3 publications in the nature publishing group journals, 2 invited by editors review articles and 2 Monographs. His work receives over 450 citations per year. During the last 5 years Dr. Shprits gave 30 solicited presentations and seminars. He is co-advising graduate students at MIT : Whitney Lohmeye, Maria De Soria-Santacruz Pich, advised graduate students at UCLA: Dmitri Subbotin, Wen Li, and Lunjin Chen, and a postdoctoral scholar Binbin Ni, Kyung-Chan Kim, Adam Kellerman, Ksenia Orlova, Alexander Drozdov and visiting scholars Marianne Daae, and Elena Kronberg who have conducted their research based on the computer codes developed by Dr. Shprits. Dr Shprits has recently served as a Main Scientific Organizer of the ST 13 session at the European Geophysical Union Assembly in Vienna, Austria; Deputy Scientific Organizer of the PRBEM1 session at the Committee on Space Research Assembly in Montreal, Canada, SM08 sessions at the American Geophysical Union Assembly in San Francisco, CA, main scientific organizer of the international IMC workshop in Espo, Finland, and UCLA, and RBSPB workshops in St. Petersburg, Russia. He is a member of the American Geophysical Union and the European Geophysical Union. In 2010 he was awarded 2010 Arne Richter Award by the European Geophysical Union, and Presidential Early Career Award for Scientists and Engineers (PECASE) in 2012.
