Specializations and Research Interests

  • Impacts of magnetospheric inputs on the ionosphere, thermosphere and mesosphere
  • Global scale solar wind: magnetosphere-atmosphere coupling processes
  • Physics of magnetic storms and the flow of energy into and through the inner magnetosphere during disturbed conditions
  • Aeronomical consequences of heavy ion and neutral precipitation at Earth and other planets (especially Mars & Venus) TIMED IDS Investigation Center for Space Environment Modeling Mars Express Aspera-3 Experiment

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
