Biography

I served 25 years in the U.S. Air Force beginning in 1976 and retiring in 2001 as a Senior Master Sergeant.  During this time I worked as a Geodetic Survey Technician for the Defense Mapping Agency assigned to F.E. Warren AFB, WY. As a Geodetic Surveyor, I deployed to locations in and outside the U.S. to position points for latitude, longitude, and elevation using conventional survey methods (pre-GPS) in support of navigation systems for missile systems, aircraft, and naval ships and submarines.  I changed career fields in the USAF in 1997 and worked as a computer programmer on the Airborne Battlefield Command and Control Center (ABCCC) in Italy and Bosnia, Yugoslavia.  I ended my career as the manager of Yokota Air Base computer network in Japan in 2000 and at Barksdale AFB in 2001.  From 2001 through 2008, I attended the University of Wyoming and completed a PhD in 2008 in Rangeland Ecology and Watershed Science. In December 2008, I began my career with USGS in Minnesota and developed numerous sediment-related studies for the U.S. Army Corps of Engineers, Minnesota Department of Natural Resources, Minnesota Pollution Control Agency, and numerous watershed districts. In 2016, I moved to the USGS office in Helena, Montana and am currently a supervisory hydrologist as the water quality unit chief supervising 11 staff, overseeing multiple water-quality related projects, and continuing to develop sediment-related studies in Wyoming and Montana.
