Monthly Speakers

Next Meeting: Mar 15, 2018

Speaker: Richard Tehan

Richard is originally from upstate, NY. He received a B.S. in chemistry at Utica College, in Utica, NY. and is now in his fourth year of a medicinal chemistry PhD program at Oregon State University, College of Pharmacy. His research is on drug discovery, chemical ecology, and the evolution of secondary metabolism of fungi in genus, Tolypocladium, which have diverse ecologies, including as mycoparasites, entomoparasites, and endophytes. He is presently focused on the isolation, structure elucidation, and biological characterization of peptide natural products produced by newly discovered tropical endophytic species of Tolypocladium. In his spare time, he enjoys hunting and photographing mushrooms.
He will speak about a few notable fungal natural products, the importance of fungal natural products in society, how fungi biosynthesize secondary metabolites, and his research on the evolution of secondary metabolism in Tolypocladium and hypocrealean fungi. He will discuss some of the compounds they produce, including compounds newly discovered in his lab, their associated ecologies and possible function in nature, as well as their biological activity in antibacterial and anti-cancer assays.
