Areas of Interest

  • Thermodynamic analyses of enzymes involved in fatty acid and amino acid oxidation including the mitochondrial membrane enzyme Electron Transfer Flavoprotein:Ubiquinone Oxidoreductase (ETF:QO) and the mitochondrial matrix enzyme Glutaryl-CoA Dehydrogenase (GCD) as a way of evaluating the molecular bases of the childhood diseases Glutaric Aciduria Types II and I and of Multiple Acyl-CoA Dehydrogenase Deficiencies. More specifically, the exploration of the role of ubiquinone binding to clinically relevant mutant and wild type ETF:QO through organic synthesis and fluorescence quenching analysis and spectroelectrochemical evaluation of the redox properties of mutant and wild type GCD. The chemical alteration of ETF:QO by reactive oxygen species (ROS) also is of interest.
  • Chemical analyses of Wisconsin’s environment, including evaluation of the lead content of various components of the contaminated Rush Lake ecosystem.
