Research Interests
Ph.D. in Physics, with specialization in Space Plasma Physics, 1993, UCLA
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. He is also studying how the lunar environment is affected by its interaction with the solar wind, critical to future manned missions on the moon.
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 while incorporating new data from the Moon's plasma environment, as part of the ARTEMIS mission. He also verees the Electron Loss and Fields Investigation CubeSat (ELFIN), funded by NASA and NSF. ELFIN is the first satellite built entirely on the UCLA campus, involving over 250 students over six years, launched on September 15, 2018. This pair of tiny satellites will study how electrons are scattered from the radiation belts by electromagnetic waves, a process which powers the aurora.
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.
