Research Overview:

Dr. Riordan’s research laboratory is exploring the roles of redox active metals, including nickel and iron in biocatalytic and stoichiometric transformations.  Frontier mechanistic problems in bioinorganic chemistry that may be probed through chemical synthesis, reactivity and kinetic studies are of primary significance.  Research at this interface requires the tools of chemical synthesis, spectroscopy and physical organic chemistry.  Current efforts include synthetic modeling of the catalytic reactivity of the nickel-containing enzyme acetyl coenzyme A synthase (ACS).  A second area of inquiry entails small molecule activation via low valent, late transition metal complexes, such as Ni(I), Co(I).  Reductive dioxygen activation at nickel represents a primary current focus.  The studies are collaborative and highly interdisciplinary.

Following his doctoral studies, Dr. Riordan was a postdoctoral fellow at the University of Chicago.  He then served on the faculty at Kansas State University coming to the University of Delaware in 1997.
