Famous for

* Co-Investigator on: LANL/GEO, POLAR/CEPPAD, POLAR/CAMMICE, & CLUSTER/RAPID investigations.
* Active in Space Weather activities including support of Air Force Technical Applications Center & 55th Space Weather Squadron and P.I. for a Los Alamos Industrial Partnership with Hughes Space Communications Co.
* Involved in analysis of data from a variety of satellites including: WIND, POLAR, GALILEO, GEOTAIL, DMSP, HEO, GPS, SAMPEX, GOES, CRRES, IMP-8, Viking, Freja, and LANL geosynchronous satellites and comparison of satellite data with ground-based observations including magnetometers and radars.
* Research topics of interest include: substorms, storms, relativistic electron events, solar proton events, effects of space environment on spacecraft and operations, radiation belt structure and dynamics, magnetic field models and mapping, and energetic particle boundaries in the magnetosphere.
* Recent studies include:

1. Energetic Neutral Atom imaging of the earth's magnetosphere using the POLAR/CEPPAD/IPS instrument.
2. Studies of radiation belt structure & dynamics and the effects on satellite systems including the Telstar 401 and Galaxy IV satellite failures.
3. Observationally testing the magnetic mapping between geosynchronous orbit and the auroral ionosphere by comparing the spectra measured at low altitude by DMSP and at high altitude by Los Alamos detectors.
4. Substorm studies ­ particularly observational determination of the size, shape, and propagation of the substorm injection region using multi-satellite observations and numerical modeling. Also numerous studies of substorm timing comparing injection times with onset times seen in Pi2 pulsations, magnetic bays, field dipolarization, ionospheric radar data, bursty bulk flows, plasmoid formation, traveling compression regions (TCRs), etc.
