Honors, Awards and Accomplishments

Fellow, American Geophysical Union
Interdisciplinary Scientist, NASA Dynamics Explorer Mission, a two spacecraft to explore the coupling between near-Earth space and the upper atmosphere
Guest Investigator, Anomalous Particle Tracer Experiment/Charge Composition Explorer (AMPTE/CCE) Mission, a joint NASA/ESA spacecraft mission that flew in the region of the radiation belts collecting information on magnetic storms, substorms and solar wind entry on the dayside of Earth
Member, TIDE (Thermal Ion Dynamics & Energetics) instrument Co-Investigator Team, POLAR Spacecraft, a component of the International Solar-Terrestrial Physics Mission, a suite of spacecraft viewing energy flow starting at the Sun's surface and ending in the Earth's upper atmosphere
Interdisciplinary Scientist, TIMED (Thermosphere-Ionosphere-Mesosphere Energetics and Dynamics) Mission, exploring Earth's middle atmosphere and effects of energy and momentum inputs from near-Earth space and lower atmosphere
Science Team Member, Aspera-3 Instrument Team, European Mars Express Mission
Main author of a spaceweather outreach site sponsored U-M's “Windows to the Universe Project,” “WeatherNet4” and Rice University's Connections Project
Created and maintain SCOSTEP S-RAMP Space Weather Clearinghouse website
Amelia Earhart Fellowship Award
Editor's Citation for Excellence in Refereeing, American Geophysical Union
Outstanding Research Scientist Award, University of Michigan * Outstanding Research Scientist Achievement Award, College of Engineering, University of Michigan
First Demonstrator of high energy oxygen ions importance in producing stable auroral red (SAR) arcs through collisions with thermal electrons at high altitudes
Discovered that subauroral electron temperature enhancement, produced through collisions with radiation belt ions, is regulated by interesting feed-back mechanisms
Showed that heating thermal ions in plasmasphere by radiation belts is two-step process
Combined observations and simulations to establish that several previously unappreciated mechanisms (ion drifts to the dayside magnetopause, precipitation into the atmosphere and abrupt changes in ring current source population) could account for rapid time-scale changes in strength of Earth's ring current/radiation belt
Discovered through simulations and observations that a remarkable increase in ring current intensity is produced by superdense plasma sheets
