Michael Welsh

Assistant Professor of Chemistry

Taylor Science Center 1075
315-859-4877

Michael Welsh’s research interests lie at the interface of chemistry and microbiology, and he is broadly interested in the biosynthesis of polymers that decorate the cell surface of bacteria. At Hamilton, he will study enzymes that build the bacterial cell wall with the goal of aiding the development of new antibiotics.

He received a bachelor’s degree in chemistry from Washington and Lee University and a doctorate in chemistry from the University of Wisconsin – Madison. Welsh then moved to Harvard Medical School as a National Institute of Health postdoctoral fellow.
