Ring Current Investigations

Vania Jordanova is a senior scientist at Los Alamos National Laboratory with over 25 years of experience bridging theoretical plasma physics, data analysis, and computational modeling. Her expertise includes geomagnetic storm dynamics and processes coupling ionospheric and magnetospheric regions. Originally from Bulgaria, she received a Ph.D. in Atmospheric and Space Sciences from the University of Michigan in 1995. Before joining the Laboratory in 2006, she spent ten years at the University of New Hampshire, teaching magnetospheric physics and investigating the geospace environment with state-of-the-art models she developed. Currently, she is the Chair of the NSF/GEM Program Steering Committee. She has more than 150 scientific publications and has given over 50 invited presentations at international conferences. She is a Co-Investigator on the NASA Van Allen Probes mission and Principal Investigator of the interdisciplinary SHIELDS (Space Hazards Induced near Earth by Large Dynamic Storms) project, winner of a R&D 100 Award in 2017.

Prof. Ilie is an Assistant Professor in the Department of Electrical and Computer Engineering at the University of Illinois at Urbana-Champaign. Her primary research is the development and application of high-performance, first principles computational models to describe and predict the conditions in near-Earth space leading to geomagnetic storms. Prof. Ilie’s research focus is on developing new approaches to study the dynamics of plasmas and electromagnetic fields in the geospace environment, and to advance the predictive capabilities of the complex dynamics occurring in the solar wind-magnetosphere-ionosphere system. She combines both theoretical and observational work to develop predictive tools that form the basis of operational warning systems and hazard mitigation. Prof. Ilie earned her Ph.D in Space and Planetary Physics from the University of Michigan and has been an NSF Postdoctoral Fellow at Los Alamos National Laboratory. She is a recent awardee of the NSF CAREER, NASA Heliophysics Early Career Investigator and Air Force Young Investigator Program awards.

Margaret Chen performs research on charged-particle transport, acceleration, and loss, and wave-particle interactions in the Earth’s magnetosphere and ionosphere. Her expertise is on developing and using computer simulation models to understand better the physical processes of such phenomena and has tested simulation results against both theory and observational data. Her work also includes applying space environmental knowledge towards analysis of satellite anomalies. Chen has authored and co-authored over 50 papers in refereed journals. She has served as a Space Science Editor for Geophysics Research Letters (2007-2010) and Editor for the 1996 COSPAR Symposium D0.5: The Subauroral Ionosphere, Plasmasphere, Ring Current and Inner Magnetosphere (Adv. Space Res., 20(3), 1997).
