Research Interests

Tuberculosis has been a long-standing problem in our country. Its complex physiology and ability to survive in hostile environments, coupled with the serious rise in multidrug-resistant (MDR) and extensively drug-resistant (XDR) tuberculosis cases, has necessitated the renewal of efforts to understand the molecular basis of its pathogenesis. To effectively treat tuberculosis, it is imperative to find newer targets, which are important for in-vivo bacterial survival and persistence. We work broadly on the following three areas.

  • Phosphorylation based signaling cascades modulated by Eukaryotic like Serine/Threonine Protein Kinases and phosphatase in Mtb, transduce extracellular stimuli to a cellular response ensuing pathogen's growth, persistence, and pathogenesis. We are interested in discovering signaling networks in Mtb and delineate how the STPKs regulate multiple cellular processes such as; cell division, cell wall synthesis, secretion, transcription, and survival in the host.
  • To effectively respond to the dynamic microenvironment of the hostile host, Mtb extensively remodels its transcriptional networks, and thus gene expression is fine-tuned in response to local environmental cues and growth conditions. We are interested in delineating the function of both non-essential and essential transcription factors in Mtb
  • A possible way to overcome the emergence of drug resistance is to combine antibiotic treatment that kills the bacteria with targeting host molecules that are necessary for the sustenance of infection, which is termed adjunct host-directed therapy (HDT). We investigate the important host pathways that can be used for HDT.
