Honours and Achievements:

  • Recipient of Postdoctoral Fellowship from Tokyo Biomedical Research Foundation (TBRF), Tokyo, Japan in 2017.
  • Recipient of Postdoctoral research residentship from Japan Agency for Medical Research and Development (AMED), Tokyo, Japan in 2015.
  • Recipient of Senior Research Fellowship from Indian Council of Medical Research (ICMR), India in 2013.
  • Recipient of International Congress of Parasitology (ICOPA) Travel Award from Japanese Society of Parasitology (JSP), Japan in 2018.


  • Contribution: He is currently investigating the project entitled as “Studyof exosomes and pathogen secreted host immunomodulatory molecules for development of future therapeutics against enteric pathogens”, funded by Japan Agency for Medical Research and Development (AMED). Amoebiasis caused by the enteric pathogen Entamoeba histolytica is one of the major enteric diseases in humans.
  • Interests: To understand in depth molecular basis of host-pathogen interaction, and to identify and validate novel therapeutics targets against enteric pathogens through state of art molecular biology, cell biology, immunology, biochemical and bioinformatics approaches.
