♦ Development, Operation, and Maintenance of an in-house custom Pulsed Electron Paramagnetic Resonance (PEPR) Spectrometer. Developed MATLAB and LabVIEW code for instrumentation control and data analysis. ♦ PEPR spectrometer utilized an electromagnetic; field controller; custom FPGA pulse programmer; microwave synthesizer, related electronics and waveguides; digital oscilloscope for data acquisition, waveform analysis, and pulse program visualization.♦ Identified and resolved 4 unique cooper coordination environments in lab synthesized Amyloid β-fibrils. Fibril design was mimicked for its potential as an electron storage device inspired by its multitude of metal complexes that can be formed within a single peptide array.♦ Captured and characterized novel intermediate cobalamin species that is sequestered by Adenosyltransferase in patients with Dysfunctional Methylmalonyl-CoA mutase for cofactor retention, observed as reduced B12 concentrations in humans.♦ Identified unique Protein-Protein complex formed by B12 trafficking proteins CblC and CblD. Spectroscopic evidence of a thiolato-cob(II)alamin elucidated role of protein complex as critical step in providing internal sulfur axial ligand to activate cofactor for B12 trafficking pathway.♦ Adapted cryogenic system to function with liquid nitrogen reducing cost of operation for higher temperature experiments and enabled new time regime PEPR capabilities for study of Mesodomain in EAL proteins.♦ Designed and generated vectors for expression of Serine based Bio-Microcompartments involved in the controlled transport of toxic reaction byproducts (ethanol) of ethanolamine lyase.

♦ Conducted research elucidating the enzymatic mechanism of Oxalate Decarboxylase. Research resulted in the development of new enzymatic mechanism for B. sub oxalate decarboxylase that identified the cleavage of the carbon-carbon bond through the redox cycling of its manganese cofactor that is facilitated by the controlled formation of superoxide during reaction.♦ Designed and developed flow cells for the use with real time kinetic measurements of free radical production. EPR spectrometer was interfaced with an HPLC for front end separation prior to collection of EPR spectra and mass spectrometry (LC/EPR/MS). Resulted in definitive confirmation of controlled superoxide and carbon dioxide radical formation of B. sub oxalate decarboxylase.♦ Identified Mn(II)/(III) redox cycling and molecular geometry elucidating coordination of metal cofactors in B. sub oxalate decarboxylase by sub-kelvin X-Band EPR (UF) and multi-frequency EPR investigations utilizing a multi-frequency/field quasi-optical broadband spectrometer at the National HighMagnetic Field Laboratory (Tallahassee, FL).♦ Solved the first crystal structure of the active pH structure of B. sub oxalate decarboxylase (in preparation for publication). ♦ Designed and developed an immobilization protocol for affinity tagged metalloenzymes for use with low temperature EPR. System is amenable to any protein sample with a His-6X affinity tag and a paramagnetic probe. ♦ Characterized and definitively identified formation and localization of hot holes and electron movement across rutile and anatase phase Ti-Oxide and Au-coated Ti-Oxide materials. Characterized photo-efficiency and viability of material to act as solar cell under visible light conditions.♦ Identified spectroscopically the formation and migration of polarons and bipolarons in true black polymer films developed for use in displays.

♦ Research resulted in 5 publications.♦ Explored the effects of short-range interactions on viscosity of small alkanes in solution. ♦ Models accounted for short-range interactions that occurred between the solute and solvent, which allowed for identification of a reliable value for intrinsic viscosity and mobility. ♦ Through the use of the Bead Method, electrophoretic mobility studies were conducted on small ions in solution, and then extended to incorporate oligopeptides. ♦ After modeling peptides in many conformations versus mobility the assumption was made that they take a cyclic conformation, as the best correlation was obtained for this data.
