Current Projects
  1. Marine Macroalgae- An underexplored source of biomolecules and beneficial organisms.
    This project is an interface of microbial biotechnology, environmental sustainability, and molecular pathogenesis. The work focuses on harnessing marine endophytic bacteria as next-generation bio-stimulants to enhance plant productivity and resilience under stress conditions. The research involves designing endophyte-driven strategies for bioremediation-contaminated ecosystems.
  2. Proteins involved in microbial pathogenesis- A biochemistry approach.
    At the molecular level, this project investigates the role of cyclic nucleotide-binding proteins in bacterial pathogenesis, with a focus on clinically and environmentally significant pathogens such as Pseudomonas, Mycobacterium, Vibrio cholerae, Salmonella, and Shigella. This work aims to unravel regulatory networks governing virulence and host-microbe interactions.
