On the research arena, my primary research interests are in mineralized tissue {bone & dentin} maintenance and regeneration and understanding the role of the extracellular matrix proteins {collagen and proteoglycans} and glycosaminoglycans in these processes and in oral diseases, such as periodontal disease and caries, dental erosion. I am also interested in dietary local delivery interventions using phytochemicals/botanicals and understanding the mechanism of their matrix modifying and cell behavior effects and how they could contribute to prevent dentin/bone degradation. Of note, via control of inflammation, ECM molecules and their biomodifications can regulate immunity.  More recently, I have engaged in development of matrix-inspired scaffolding for dentin and bone repair/regeneration applications.
