In 1979, I began my career as a mushroom grower for Leaver Mushrooms, Ontario, Canada. In the early 1990’s I left Leaver as the Director of Growing to pursue a PhD in mushroom research at Penn State University.
As a Professor of Mushrooms my research and extension programs cover all aspects of mushroom growing, from composting through production, including disease management.
Recently we secured a 5 year, $1.4 million grant from the USDA to study mushroom flies and diseases; a project that is a collaboration of researchers at Penn State in Plant Pathology and Environmental Microbiology, Entomology and Food Science.
Other ongoing research projects include the reuse of compost and casing to produce a second crop of mushrooms; alternative materials for mushroom substrate and the study of cultural factors influencing a new mushroom pathogen, identified as Syzygites megalocarpus.
My extension program includes grower educational workshops and the annual Mushroom Short Course. I have been fortunate enough to work with mushroom growers around the world who continue to amaze me with their intuition and resourcefulness.
