Research Interests

  • Biofilm evolution
  • Biofilm-material interactions
  • Development of long-term in vivo biofilm-host model
  • Biofilm response to mechanical, chemical and antimicrobial agents
  • Symbiotic relationship of non-pathogenic biofilms and host, and potential applications.
  • In-vivo and in-vitro biofilm imaging
  • Human Microbiome

My current research focus is based on Biofilm research. Biofilms are dynamic, evolving communities of bacteria that are poorly understood. I hope to help better understand how biofilms form, evolve, and interact with materials (dental materials) and how they develop in confined geometries. When the community is presented with a mechanical (ex. Shear stress) or chemical (antimicrobial) challenge, how do they respond? How do the cells within the community modify to adapt and evade the stressor and what role does the surface or geometries of the material play?
