Welcome to the Dey Lab at the Department of Chemistry, The University of Iowa.

Our research interests lie at the interface of chemistry and biology and we are investigating the molecular mechanisms of metalloenzymes important for bioenergy conversion, human health and disease, or environmentally valuable. We apply a combination of enzymology, biochemistry, microbiology, molecular biology, and structural techniques to probe biological processes on a molecular level. Our research is highly interdisciplinary, drawing from synthetic chemistry, protein biochemistry, biophysics, and microbial bioprocessing.
