Michael Welsh serves as Assistant Professor of Chemistry at Hamilton College since his 2019 appointment, with dual affiliations in Chemistry and Biochemistry/Molecular Biology. His research bridges chemical and microbiological disciplines to combat antibiotic resistance through bacterial cell envelope studies.
His academic credentials include:
- Ph.D. in Chemistry from University of Wisconsin, Madison
- B.S. in Chemistry from Washington and Lee University
Welsh's research program focuses on enzymatic mechanisms of bacterial cell wall biosynthesis, particularly peptidoglycan assembly by shape, elongation, division, and sporulation (SEDS) family glycosyltransferases and penicillin-binding proteins. His work employs chemical biology approaches to disrupt quorum sensing in pathogens like Pseudomonas aeruginosa, aiming to develop novel antibiotic strategies targeting virulence rather than viability. This interdisciplinary methodology integrates synthetic chemistry, enzymology, and microbial genetics to address critical challenges in antimicrobial resistance.
His publication record demonstrates consistent focus on bacterial envelope biogenesis and chemical intervention strategies, with recent work emphasizing target validation for antibiotic development and environment-dependent quorum sensing modulation. These studies span biochemistry, chemical biology, and infectious disease research, reflecting his commitment to translating molecular insights into therapeutic applications.
Scientific recognition includes:
- NIH Ruth L. Kirschstein-NRSA Postdoctoral Fellowship (F32), 2016
Welsh teaches foundational chemistry courses including Principles of Chemistry while maintaining active research mentorship. His professional engagement includes membership in the American Chemical Society, and his laboratory at Taylor Science Center 1075 develops chemical tools to probe bacterial communication systems and cell wall assembly pathways.
