He has given numerous lectures on the subjects of mineralogy and optical mineralogy over the past 35+ years to local earth sciences groups, colleges, and at the U.S. Geological Survey.
He has an extensive publication record in the fields of mineralogy, geology, and environmental chemistry since 1984, with nearly 150 journal articles and abstracts published in peer-reviewed journals, including the American Mineralogist, Canadian Mineralogist, Geochimica et Cosmochimica Acta, Rocks & Minerals, and The Mineralogical Record. He wrote an extensive monograph on the evolution of the petrographic microscope, which was published by The Mineralogical Record in 2003.
