Ph.D., Physics, University of California, Berkeley, 1977.
Asst. Res. Physicist, Space Science Lab, UC Berkeley, 1977 - 8.
Member of the Technical Staff, Space Science Lab, The Aerospace Corp., Los Angeles, 1978-82
UW Faculty since 1982

Experimental space plasma physics, atmospheric and magnetospheric electrodynamics, middle atmosphere electrodynamics, thunderstorm and lightning electrodynamics.

My research involves the experimental investigation of electrical parameters in the Earth's environment, in particular, the study of the electromagnetic energy flow that couples separated environments such as the atmosphere, the ionosphere, and the magnetosphere. Active projects include: Sprite balloons (NSF sponsored) involving stratospheric balloon flights from Brazil to study the electrodynamic environment above sprite producing thunderstorms, a study of NLC (Noctilucent Clouds) and PMSE (Polar mesospheric summer echos) with two rockets from Norway in 1999 (NASA sponsored), Electric field measurements in Antarctica with the Polar Patrol Balloon program of with U. Houston and NIPR, Japan; MINIS balloon experiment studying 'killer electrons' with four balloon flights from SANAE station in Antarctica in December 04 (with UC Berkeley and U. Houston and many others) (NSF Sponsored); C/NOFS Optical Lightning Detector in the VEFI electric field experiment to be launched Nov 2004 into equatorial orbit to study ionospheric irregularities (NASA and USAF sponsored), Sounding Balloons to study thunderstorm electric fields, with three flights to be in may 2004 with NSSL in Norman, OK (Mindlin Foundation support), and the latest effort: global lightning location using VLF techniques with the WWLL (World Wide Lightning Location network) now being managed by my group (see webflash.ess.washington.edu for more information).

 Students are encouraged to be vitally involved in hardware production and data analysis in all of these projects. All instruments are built in our lab by the students or the professional engineering staff. Most projects include the opportunity for student travel.
