Research Area

Microbial Ecology & Infectious Diseases

Research on the ecology, persistence, and transmission of clinically important bacteria in Bangladesh, with a central focus on Vibrio cholerae and the environmental drivers of cholera.

Scientific questions

  • How do toxigenic Vibrio cholerae cells persist in aquatic environments between epidemics?
  • What role do quorum sensing and autoinducers play in bacterial survival and resuscitation?
  • How do bacteriophages and biofilms shape pathogen ecology and transmission?
