James Penner-Hahn (B.S. Purdue, Ph.D. Stanford) is Professor of Chemistry and Biophysics and Associate Dean for the Natural Sciences in the College of Literature, Sciences, and the Arts.
Metal ions play a critical role in most biological reactions, particularly those associated with energy conversion. His group's research focuses on using spectroscopic methods (particularly x-ray absorption and electron paramagnetic resonance) to understand the structure and reactivity of biological metal sites, and on using x-ray nanoprobe imaging methods to characterize the distribution and speciation of transition metals in intact biological tissue and cells on the nm distance scale. They make extensive use of synchrotron radiation, using the unique resources available at synchrotron laboratories in the U.S. (Brookhaven, Argonne, Stanford and Berkeley) and abroad (Japan, France).
