I am currently Professor of Oral Biology at the Section for Oral Biology and Pathology. I am engaged in laboratory-based and clinical research on the role played by microbial biofilms (dental plaque) in development of the oral diseases, caries and periodontitis (gum disease). My primary interests are: the role of oral streptococcal adhesins in early biofilm formation, adaptation in oral bacteria in response to interactions with salivary proteins and the development of proteolytic activity in biofilms in periodontitis and infections associated with dental implants (peri-implantitis). I am involved in teaching of dental students in areas such as cell biology, tooth development, mucosal biology and salivary biochemistry.
