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.  

Research Interests
My group's research falls within the general field of bio-inspired inorganic chemistry.  The common theme is the synthesis and characterization of inorganic complexes that mimic the structure and/or function of metalloenzymes.  All of our projects are multifaceted, combining inorganic coordination chemistry with mechanistic studies, spectroscopic characterization (UV-vis, EPR, MCD, X-ray absorption, resonance Raman), and computational (DFT) analysis.
