    • Brief Biography

    Dr. Vadim M. Uritsky received his Ph.D. in Space Physics and Geophysics from St. Petersburg State University, Russia in 1998. In 1999-2001, he held a postdoctoral research position at NASA / Goddard Space Flight Center, Greenbelt, MD. In 2002-2005, he continued his research as a senior staff scientist at the Institute of Physics of St. Petersburg State University. In 2005, Dr. Uritsky defended his post-doctorate habilitation thesis and was granted the title of Doktor Nauk (Grand Ph.D.). In 2006 - 2011, Dr. Uritsky was a senior research associate and an adjunct (research) professor in the Department of Physics and Astronomy of the University of Calgary, Canada. In 2011-2013 he was a Research Associate with the Institute for Astrophysics and Computational Sciences operating within the Department of Physics at Catholic University of America (CUA). In 2013-2023, V. Uritsky was an Associate Professor in the CUA's Department of Physics. He is an ordinary (full) professor in the same department since 2023.
