Biography

James E. Penner-Hahn is the George Lindsay Professor of Chemistry at the University of Michigan, focusing on Bioinorganic Chemistry, Biophysical Chemistry, Energy Science, Inorganic Chemistry, Materials Chemistry, Optics, Imaging, and Physical Chemistry. His research primarily investigates the roles of trace metals such as Mn, Fe, Co, Ni, Cu, and Zn in biological systems, with a significant focus on metalloenzymes. These enzymes catalyze reactions with exceptional speed and selectivity compared to traditional catalysts, and Penner-Hahn aims to uncover the structural and functional relationships within these metal-active site structures. He utilizes advanced techniques, including X-ray absorption spectroscopy, to examine metal distribution in biological tissues at sub-cellular levels. His work has contributed to the emerging field of inorganic physiology, which examines the transport and storage of metal ions in living organisms. Additionally, he studies the dynamics of photoactive metal sites and employs synchrotron radiation for time-resolved examinations of molecular structures.
