I was born in 1939 in Ann Arbor, Michigan and grew up on a small farm nearby. By age 6 I was smitten by the stars, and astronomy became a life-long hobby. I graduated from the University of Michigan with an astronomy degree in 1961. A 2-year stint at the U.S. Naval Research Laboratory in Washington DC was followed by 2 years at Caltech's Jet Propulsion Laboratory. I worked briefly at Cornell University's Arecibo Observatory in Puerto Rico, and then returned to work at the Jet Propulsion Laboratory until retirement 32 years later, in 1998.
My 38 years of employment were in several fields: radio astronomy, atmospheric boundary layer remote sensing, aviation safety and airborne atmospheric science. I have over 100 peer-reviewed publications in scientific journals, four patents and numerous awards. The highlight of my pre-retirement career is participation as a principal investigator in all of the NASA-led international campaigns of airborne studies of stratospheric ozone depletion - commonly referred to as "the ozone hole." The airborne instrument that I developed was helpful in determining that man-made chemicals (chlorofluorocarbon, CFC) are responsible for the ozone hole. Another accomplishment during my career was the creation of an avionics instrument for warning and avoidance of "clear air turbulence," CAT, which is described in two of my patents.
After retirement I resumed the childhood hobby of astronomy, and moved to Arizona where I have constructed a 2-dome observatory in my backyard. My participation in a professional/amateur project (XO) led to co-authorship of discovery papers of five exoplanets (planets that orbit other stars). I recently consulted as a Visiting Scholar for a university by observing a list of exoplanet candidates and dwarf eclipsing binary stars. My publication rates before and after retirement are comparable, so in effect I haven't retired.
