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 ground-based, balloon, rocket and satellite experiments to study atmospheric and space electrodynamics especially as relates to lightning (World Wide Lightning Location network) (see for more information and recent summary at the 2016 GLM meeting).

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