Research and Practice Interests

I studied roles of the complement system in the pathogenesis of F. tularensis. This deadly bacterium is given the highest research priority classification by the CDC as a Category A Select Agent. Most successful human pathogens have evolved molecular mechanisms to subvert, inactivate, or exploit proteins of the complement system. Working in biosafety level 2 and 3 laboratories, my dissertation project was fourfold: 1) to identify complement components activated by specific bacterial surface moieties expressed by F. tularensis and to characterize the relative involvement of subsequent pathways within the overall complement system; 2) to identify resistance mechanisms to the bactericidal effects of complement; 3) to elucidate the functional activities of primary human macrophages in response to complement-mediated phagocytosis of F. tularensis; and 4) to study human bronchoalveolar lavage fluid in order to identify potential modulatory effects of distinct innate immune molecules present within the lung.
I studied environmentally pervasive halogenated aromatic hydrocarbons and associated toxic mechanisms involving the metabolic generation of reactive oxygen species and the formation of genotoxic DNA-binding metabolites. In vivo model systems included genetically modified mice containing targeted cytochrome P450 system gene deletions, "humanized mice" containing human gene insertions, and various secondary cell lines. In vitro model systems were developed by isolating subcellular fractions both from cell lines and from excised murine organs containing oxidoreductase enzyme systems that are associated with the intracellular endoplasmic reticulum and mitochondria. My thesis work focused on relative reactive oxygen generation via uncoupled redox reactions involving the environmental toxins TCDD and polyhalogenated biphenyls and specific inducible and constitutive cytochrome P450 enzymes including CYP1A1, CYP1A2, and CYP2E1.
