Research Interests: Oral Microbiome, Pathogenesis, and Inflammation

My research interests involve understanding the role of the oral microbiome and its contribution to the etiology of periodontitis, a prevalent condition characterized by a polymicrobial-driven infection and inflammation of gum tissues. This condition is associated with a dysbiotic microbiome leading to the emergence of a virulent community of oral bacteria, known as periodontopathogens. These pathogens have been implicated in the development of other systemic inflammatory diseases, such as Alzheimer's disease and rheumatoid arthritis.

For successful infection and inflammation of the gum tissue, periodontopathogens have evolved pathoadaptive mechanisms through which they persist in the infected sites. Nevertheless, these mechanisms remain largely unknown.  Previous studies have indicated that cobalamin (Vitamin B12) transporters are highly active microbial components in the periodontal pockets of individuals with periodontitis. Our research provided the first glimpse into the biological significance of cobalamin in the pathogenesis of these pathogens, which awaits further investigation.

Currently, my research focus is directed toward elucidating the biological significance of cobalamin, a prominent redox regulator, in the pathoadaptation and pathogenesis of periodontopathogens, particularly Porphyromonas gingivalis considered a keystone pathogen. My research holds the potential to introduce novel key targets in periodontopathogens for the development of innovative therapeutics.
