|Professor Harms received B.A. and M.S. degrees from S I U- Edwardsville, and his Ph.D. from UMSL. He joined the UMSL chemistry faculty as Assistant Teaching Professor in 2019 following the completion of his doctoral degree. While a graduate student at UMSL, he taught advanced chemistry courses at both UMSL and SIUE.||
Professor Harms research has focused on the collection and interpretation of high-resolution spectra of small, metal-containing molecules in the gas-phase using a technique called intracavity laser absorption spectroscopy. His recent work has examined 5d transition metal compounds, characterizing deviations from quantum mechanical models that result from the breakdown of the Born-Oppenheimer approximation and the differences in nuclear size between different metal isotopes.
