Brief Bio

Dr. Le has authored or co-authored over 100 peer reviewed scientific publications and technical papers. Her research interests include magnetospheric current systems; ULF waves in the region upstream of collisionless shocks, in the magnetosphere and on the ground; the Earth's magnetopause, polar cusp and boundary layers; solar wind-magnetosphere-ionosphere coupling; and plasma irregularities in equatorial ionosphere. Her research activities primarily involved the analysis and interpretation of spacecraft data and ground-based magnetic field data as they relate to these research areas. She has been involved in flight teams for six NASA missions. She is currently the Project Scientist for Geotail mission, the Deputy Project Scientist for Magnetospheric MultiScale (MMS) mission, and a science Co-Investigator for Communication/Navigation Outage Forecast Satellite (C/NOFS) mission.
