Research Interests
I am trained as both an Infectious Disease specialist and as an expert in innate defense against bacterial infection, with a focus on Gram-negative organisms. As an Infectious Disease specialist, I am particularly interested in treatment approaches to multidrug-resistant Gram-negative infections. As a researcher, I study the innate defenses against these types of infections. In one project, I study the Bactericidal/Permeability-Increasing protein (BPI) - an endogenous antibiotic found in neutrophils and available in recombinant form. BPI has potent activity against Gram-negative bacteria, including multidrug-resistant clinical isolates I collect.
I have a 3-year grant from the Bankhead-Coley Research Council entitled "The Role of Smoking in the Promotion of Crohn's Disease: A Predisposing Factor to Colon Cancer." The study population consists of Crohn's Disease patients who are seen in the GI clinic at UF and who have been genotyped for the major Crohn's Disease polymorphisms as part of a separate study. In the first part of my study, I am performing chart reviews of these patients to score their disease severity. This scoring system includes smoking status and the data are analyzed based on that variable as well as their genotypes. In the second part of the study, monocyte-derived macrophages from these patients will be assessed for their ability to kill enteric bacteria and elicit pro- and anti-inflammatory cytokines.
I have expertise in the area of Campylobacter jejuni pathogenesis, and study the role of innate immune mechanisms including reactive nitrogen species, BPI and most recently, autophagy in host defense against C. jejuni infection.
