Faculty & Research

Faculty (With sidebar)

Research in the Department of Chemistry is loosely organized according to seven paths: analytical, chemical biology, chemistry education research, inorganic, materials, organic and physical chemistry. Faculty are often affiliated with more than one of these seven paths, as summarized below. They also explore a wide array of research topics, which branch out into other areas including astronomy, medical science, pharmacy, and physics, to name a few.
