Biomedical Devices; bio-MEMS; biosensors; Drug Delivery; Advanced Characterization. Dr. Sulchek's research focuses primarily on the measurement and prediction of how multiple individual biological bonds produce a coordinated function within molecular and cellular systems. There are two complementary goals. The first is to understand the kinetics of multivalent pharmaceuticals during their targeting of disease markers; the second is to quantify the host cell signal transduction resulting from pathogen invasion. Several tools are developed and employed to accomplish these goals. The primary platform for study is the atomic force microscope (AFM), which controls the 3-D positioning of biologically functionalized micro- and nanoscale mechanical probes. Interactions between biological molecules are quantified in a technique called force spectroscopy. Membrane protein solubilized nanolipoprotein particles (NLPs) are also used to functionalize micro/nano-scale probes with relevant biological mediators. This scientific program requires the development of enabling instrumentation and techniques, which include the following: Advanced microscopy and MEMs; Nanomechanical linkers, which provide a convenient platform to control biomolecular interactions and study multivalent molecular kinetics; Biological mimetics, which provide a simple system to study cell membranes and pathogens. UltIMaTely, this work is used to optimize molecular drug targeting, improve chem/bio sensors, and develop more efficient pathogen countermeasures.

Jake Soper

Jake Soper

Jake D. Soper is an Associate Professor in the School of Chemistry and Biochemistry at the Georgia Institute of Technology. Prof. Soper’s research program is a hybrid of organometallic and inorganic coordination chemistry, at the forefront of an emerging area that uses redox-active ligand complexes for redox control in bond activation and functionalization reactions. His research focuses on the development of new homogeneous catalysts for selective transformations of small molecules, with particular emphasis on multielectron reactions relevant to organic synthesis and energy conversion and storage. Recent research accomplishments include the rational design of Earth-abundant metal catalysts to functionally mimic palladium in coupling catalysis cycles and the demonstration of redox-active ligand-meditated radical control in catalytic dioxygen activation and oxygen atom transfer reactions. This research has appeared in top peer-reviewed chemistry journals, including the Journal of the American Chemical Society and Inorganic Chemistry. Prof. Soper has also been an invited contributor to special issues of the European Journal of Inorganic Chemistry on Cooperative & Redox Non-Innocent Ligands in Directing Organometallic Chemistry and an Inorganic Chemistry Forum on Redox-Active Ligands, consisting of “papers from leading scientists on a multidisciplinary topic of growing interest. His recent development of redox-active ligand-mediated cobalt cross coupling catalysis was hailed as a “breakthrough in the field” in a 2011 Highlights feature in Angewandte Chemie International Edition. 

Prof. Soper earned a B.S. degree in chemistry from Western Washington University in 1998 and a Ph.D. in inorganic chemistry from the University of Washington in 2003. His graduate research was performed under the direction of Prof. James M. Mayer. He was subsequently an NIH Ruth L. Kirchstein Postdoctoral Fellow in the laboratories of Prof. Daniel G. Nocera at the Massachusetts Institute of Technology. In 2009 his independent research was honored with an NSF CAREER award and a DARPA Young Faculty Award (YFA). During his tenure at Georgia Tech, he has been invited to speak at 30 universities and 12 conferences, including four Gordon Research Conferences. He was the corresponding organizer of a symposium on modern redox-active ligand chemistry that was presented at the International Chemical Congress of Pacific Basin Societies, Pacifichem 2010. He created and directs the Georgia Tech–Westlake HS Energy Challenge Program, for which he received the 2010 Georgia Tech Faculty Award for Academic Outreach.

Associate Professor and Associate Chair for Operations
Additional Research
Solutions to outstanding problems in benchtop-scale organic synthesis, pharmaceuticals and commodity chemicals production, petroleum manufacturing, and energy generation and storage all hinge on the development of new methods to selectively transform the chemical bonds in small molecules. Because selectivity in redox bond activation and functionalization reactions typically derives from 1e– versus 2e– redox control, the function of most synthetically useful transition metal catalysts is to mediate 2e– bond making and breaking while suppressing potentially competing 1e– reactions.The Soper Group reengineers the way transition metal catalysts impart selectivity in redox bond activation and functionalization reactions. Instead of suppressing 1e– transfer, we use the capacity of some metal–ligand combinations to undergo reversible low-energy electron transfer for kinetic control in free radical reactions. We apply these methods for controlled radical chemistry to stoichiometric and catalytic reactions that are challenging or inaccessible using current methods. Recent successes include:Earth-Abundant Coupling Catalysis. Palladium-mediated 2e– oxidative addition and reductive elimination steps form the basis for numerous coupling cycles leading to selective assembly of C–C bonds. We discovered that redox-active aminophenol-derived ligands can be used to effect palladium-like 2e– oxidative addition and reductive elimination reactions at square planar later first row metal centers. These elementary reaction steps have been utilized for development of unusually well defined cycles for cobalt cross coupling of alkyl halides with alkyl- and arylzinc halides, as well as manganese and iron catalyzed aerobic coupling of aryl Grignard reagents.Metal Oxyl Radical Coupling. Recent theoretical studies suggest transition metal oxyl radicals containing unpaired electron density at oxo are critical precursors to O–O bond formation in water oxidation catalysts. Through the use of redox-active ligands, we have been able to generate a new class of well-defined coordination complexes that exhibit oxyl radical reactivity. We recently showed that a rhenium oxyl reacts with carbon free radicals to make C–O bonds at the oxo ligand, and we demonstrated that that radical character in the metal–oxo bond leads to kinetic reactivity that is not rationalized by ground-state thermodynamic considerations.O2 Activation and Aerobic Oxidations. A challenging step in many oxygenase-type redox catalysis cycles is bimetallic cleavage of the dioxygen O–O bond to generate two transition metal oxo complexes. This reaction is also relevant to energy conversion and storage in artificial photosynthetic schemes because the kinetics of O2 electroreduction at fuel cell anodes are often poor. We have demonstrated how the ability of redox-active ligands to undergo reversible 1e– transfer can be used to bring about bimetallic O2 homolysis by lowering the kinetic barrier to formation of 1e– reduced O2 complex intermediates. We are applying this method to the development of new aerobic oxidation catalysis cycles and electrode materials for efficient for O2 reduction.To accomplish these goals, researchers in the Soper Group are skilled in the synthesis and handling of air-sensitive materials. We use a variety of spectroscopic techniques to characterize reaction products and intermediates and to perform detailed mechanistic studies.
