Professional Summary:

I began my career as a general Medical Technologist and eventually specialized in clinical bacteriology in local hospital. I returned to school to earn an MS in Medical Technology specializing in Microbiology. I continued to work weekends in the hospital while working as a research technician in immunodermatology. I pursued further graduate work and earned a PhD degree in Microbiology from UB. During my thesis work I became interested in molecular mechanisms of infectious disease. As a post-doc I focused on characterizing the genes of the fimbrial operon and biofilm formation by the periodontopathogen Aggregatibacter actinomycetemcomitans. Currently I am working on gene regulation in A. actinomycetemcomitans by small non-coding sRNA. We have recently used RNAseq investigate the effect of amylase on Streptococcus gordonii and DNAseq to explore the phylogeny of amylase-binding proteins in the same bacteria.

Research Profile

Biofilms are communities of bacteria attached to a surface enclosed in a matrix of extracellular polysaccharides (EPS), DNA dissolved nutrients and other biological molecules. Biofilm-associated organisms cause up to 80% of all infections. Dental plaque is a typical multispecies biofilm. The focus of our research is to define the molecular basis of biofilm formation by the periodontopathogen Aggregatibacter (Actinobacillus) actinomycetemcomitans. This organism is associated with localized aggressive periodontitis, a destructive form of periodontitis occurring primarily in adolescents, some forms of refractory periodontitis, and is a causative agent of a variety of extra-oral infections including endocarditis abscesses and septicemia. We have shown that biofilm varies quantitatively in response to environmental conditions commonly found in the oral cavity, including variable pH, nutrient availability, oxygen tension and iron. Primary biofilm determinants include fimbriae and lipopolysaccharide (LPS) involved in adhesion, along with EPS that serves in intercellular aggregation and as a protective barrier for the cells of the biofilm. We are investigating the role of small non-coding RNA in the post-transcriptional regulation of biofilm determinant genes (fimbriae, LPS and EPS) in response to iron-limited conditions. Through the use of molecular biology techniques, protein analysis, bioinformatics, and microarrays we aim to identify the pathways involved in the maintenance of biofilm by these sRNAs. We also have used the Calgary device and other microtiter systems to evaluate the antimicrobial efficacy of a new therapeutic agent against monospecies biofilms of oral microorganisms.
