Professor Fiedler received his Ph.D. degree in inorganic chemistry under the direction of Thomas Brunold at the University at Wisconsin-Madison in 2006. After graduating from Madison, he began an NIH postdoctoral fellowship in the laboratory of Prof. Larry Que, Jr. at the University of Minnesota, where synthesized and characterized high-valent iron complexes with relevance to oxygen activation in biological systems. He joined the faculty at Marquette University in August 2009. Professor Fiedler’s research interests are in the area of synthetic bioinorganic chemistry, spectroscopy, and computational methods.  Dr. Fiedler has received external research funding from the NSF and NIH, and currently serves as chairperson of the Chemistry Department.
