Research Interests:

A complex community of bacteria lives below the gum line in the sandwich environment between teeth and periodontal tissue.  This bacterial community, known as the periodontal microbiome, has a major influence on oral health and a range of inflammatory diseases. The host inflammatory response and the periodontal microbiome interact bidirectionally. Balanced interactions between inflammatory response and the periodontal microbiome are present in oral health, whereas imbalanced interactions are linked to inflammatory disease states.  My research interest is focused on studying, at molecular and cellular level, factors that influence the primary defense responses and immune homeostasis.  We examine the impact of immunostimulants and signaling components produced by the periodontal microbiome on the regulation and function of innate immune cells and non-immune cells. In addition, we study metabolic and genetic reprogramming of host cells and periodontal pathogens imposed by inflammation. The goal of our studies is to advance the identification of diagnostic biomarkers and therapeutic targets and develop novel therapeutics to overcome chronic inflammations and infections.

Our research is interdisciplinary. It requires leveraging innovative system-based approaches and integrating the tools of molecular/cellular biology, microbiology, immunology, biochemistry, and bioengineering.

Our current projects focus on:

  1. Impact of LPS heterogeneity and secondary messengers on innate immune responses in the context of gum infections and inflammation
  2. Metabolic and genetic adaptations in the context of host-microbe interactions and chronic inflammation
  3. Key ecophysiological signals within subgingival niche promoting virulent bacterial community and pro-inflammatory responses
  4. Harnessing biosynthesis, modification, and regulation of biopolymers and self-assembly building blocks for developing novel antimicrobials and anti-inflammatory therapeutics
