Dr. Dorothy Tuthill


Dr. Dorothy Tuthill is Associate Director of the Biodiversity Institute, charged with developing and delivering programs for students, kindergarten through high school. She is an alumna of the University of Wyoming Department of Botany, with research focused on soil microfungi. After discovering that it is nearly impossible to identify some fungi, she narrowed her field to systematics and identification of species in the genus Penicillium. You may know Penicillium as the organism responsible for the delicious taste and texture of blue, camembert and brie cheeses, or the producer of penicillin, but most species live in natural environments, where they perform essential but mysterious functions involving decomposition.

Raised by entomologists and broadly trained in botany, Dorothy thoroughly enjoys sharing her enthusiasm for the natural world with students of all ages, and especially likes looking at the often missed tiny things.

Dorothy is currently serving as president of the Wyoming Native Plant Society, and also serves on the Board of the American Penstemon Society.
