 Vassilis Angelopoulos, Professor of Space Physics

Professor Angelopoulos's current research aims to understand how particles are accelerated in Earth's magnetosphere, how the upper atmosphere and ionosphere respond to space currents, and how the lunar environment is affected by its interaction with the solar wind. Professor Angelopoulos holds appointments at the Space Sciences Laboratory, UCB and at the NASA/Jet Propulsion Laboratory.

He has been the Principal Investigator of THEMIS, the scientific and technical lead of this NASA/MIDEX mission, since its inception in 2001. He is currently working on storms and substorms at Earth, and on the development of a new mission, called ARTEMIS, to study the lunar environment with two satellites.

Prior to joining the University of California in 1995, Angelopoulos worked at the Applied Physics Laboratory from 1993-1995. He received the American Geophysical Union’s Macelwane medal in 1993 and the Zeldovich medal by the Russian Academy of Science and COSPAR in 2001. When not working, he enjoys playing music, solving puzzles, reading fiction, mountain bike riding and playing basketball with his two children, Nikolas and Constance.

Ph.D. in Physics, with specialization in Space Plasma Physics, 1993, UCLA.
