Steven D. Kohl

Associate Research Scientist
Division of Atmospheric Sciences

As an Associate Research Scientist and supervisor for the Environmental Analysis Facility (EAF) at the Desert Research Institute (DRI), Mr. Kohl's responsibilities include: assisting in proposal development; preparing budget estimates; prioritizing projects for daily analysis; performing chemical analysis of aerosol samples by x-ray fluorescence; conducting blank subtraction, error propagation, and data validation; and preparing reports. He maintains the field sampling equipment, conducts training on the operation of different types of aerosol sampling systems, provides instrument trouble-shooting, coordinates sample shipping and receiving, and manages field studies. Before coming to DRI, he developed fluorescence-based immunochemical assays for use in fiber optic biosensors for environmental monitoring applications for the U.S. Environmental Protection Agency. In the U.S. Air Force, Mr. Kohl was responsible for the installation, maintenance, modification, and flight inspection of commercial and Air Force meteorological and navigational systems until he was honorably discharged with the rank of Staff Sergeant and a Top Secret security clearance.
