Research Description

My Ph.D. research at Bose Institute, University of Calcutta, India, focused on signal transduction of Mycobacterium tuberculosis. I joined Dr. Roger Pechous as a post-doctoral fellow in May, 2017. In the Pechous lab, I study the pathogenesis and progression of pneumonic plague. Yersinia pestis, when transmitted through aerosols can cause primary pneumonic plague. The disease is characterized by an almost asymptomatic pre-inflammatory phase followed by the rapid onset of a pro-inflammatory phase which can be fatal without immediate treatment. We are trying to find answers to fundamental questions like,

  •   What are the early host-pathogen interactions that dictate the pre-inflammatory phase?
  •   How does the switch to the pro-inflammatory phase occur?

I am developing an ex vivo human lung tissue platform to study early interactions of the bug with the human lung environment. At the same time, I am exploring the differences in pathogenesis of Y. pestis and Y. pseudotuberculosis because the latter fails to establish a fatal infection in the human lung.
