Research Interest/Area

Exopolysaccharides; biomolecules, chronic wounds, host-pathogen interactions, biofilm, quorum sensing, microbial genomics and microbiome


Dr. Rekha P.D, the Director of the Yenepoya Research Centre at Yenepoya University, has made significant contributions to the field of research during her tenure at the institution. Her research work encompasses various areas of study, with a focus on biopolymers in wound healing, biofilm dynamics, virulence in uropathogens, host-pathogen interactions, quorum sensing, and microbial genomics. She has conducted extensive studies to understand the role of different biopolymers in promoting wound healing processes both acute and chronic wounds. Her research explores the development of novel formulations and biomaterials that can effectively facilitate wound healing and tissue regeneration. This research holds significant potential for clinical applications and has the potential to improve patient outcomes. Dr. Rekha’s research also involves understanding the dynamics of biofilms and virulence among uropathogens to explore the host adaption mechanisms of uropathogens. Biofilms are complex communities of microorganisms that can form on various surfaces, including medical devices, and are notoriously difficult to treat. Her research contributes to the development of strategies to combat biofilm-related infections using quorum sensing based targets with aim of combating antimicrobial resistance due to biofilm related infections. Furthermore, Dr. Rekha with her team investigates the intricate interactions between host and pathogen, focusing on understanding the molecular mechanisms involved in normal and cancer cells. This research provides insights into the host’s defense mechanisms against invading pathogens and aids in the development of targeted therapeutic interventions including prebiotic based approaches. Her work has the potential translational value with local and global significance and can pave the way for the development of innovative approaches to combatting infectious diseases.
