Current Research Interest

  • CTX prophages, genome diversity and evolution of new hybrid pathogenic Vibrio cholerae clones.
  • Molecular basis of stringent response in V. cholerae and the role of (p)ppGpp in regulation of gene expression related to growth, virulence, quorum sensing and biofilm formation.
  • Molecular studies on replication origins of V. cholerae and its use for various purposes.
  • Molecular basis of survival and growth of V. cholerae cells under nutritional competition.
  • Cold shock response and cold shock proteins of V. cholerae.
