Research Theme

Research Interests

My research interests focus on the role of the acid tolerance response of Streptococcus mutans , the principal agent of dental caries. Using a variety of molecular biological, biochemical and in silico technologies we are also unraveling the mechanisms of cell-cell signaling and its role in biofilm formation and genetic exchange by gram positive pathogens. Ongoing collaborative programs also include the search for potential vaccine targets for Streptococcus pyogenes infections and the effects of dental restorative materials on bacterial growth and metabolism. Our work is also integrated with the University of Toronto Tissue Engineering Group focusing on the development of novel biomaterials resistant to bacterial infection.
