Professor David Sherman explores biochemical pathways of marine microorganisms with the goal of finding new drug candidates to treat infectious diseases and cancers. To collect the samples he needs for his work, he often trades his lab coat for a wet suit and travels to exotic locations rich in biodiversity resources. Sherman is a faculty member in the Life Sciences Institute (LSI). He also is the Hans W. Vahlteich Professor of Medicinal Chemistry and associate dean for research and graduate education in the College of Pharmacy. (Text by Laura Williams.)
