Atmospheric Measurement & Data Sciences


I joined the Pacific Northwest National Laboratory (PNNL) in 1984. My areas of specialization and interest include millimeter wave radar, meteorological instrumentation, remote sensing, microprocessor technology, digital electronics, analog electronics, and automatic control theory. I also have extensive project management experience with projects up to $5M. I am currently the leader for the Atmospheric Radiation Measurement (ARM) Program's Radar Group.

I served in the U.S. Marine Corps for four years followed by six years in the U.S. Naval Reserve as an Engineering Duty Officer.
