Dr. Bappaditya Dey


Tuberculosis and Other Zoonotic Diseases of Livestock: Molecular Pathogenesis and Intervention Strategies.


Education and training:

After graduating in Veterinary Sciences (B.V.Sc & A.H., 2002) from West Bengal University of Animal & Fishery Sciences, Kolkata Dr. Dey completed his masters in Animal Genetics and Breeding (MVSc, 2004) from CCS-Haryana Agricultural University, Hissar and subsequently, obtained his doctoral degree in Biochemistry (Ph.D, 2010) from University of Delhi, New Delhi. He continued his training in the same institute initially as a research associate and later as a Scientist-C until he moved to USA as a Post-doctoral Fellow at the Center for Tuberculosis Research, Johns Hopkins University, Baltimore (Feb. 2011-May. 2016). Subsequently, he worked as a Senior Research Scientist at the National Emerging Infectious Disease Laboratories (NEIDL), Boston University, Boston, USA (till Apr. 2017). Dr. Dey joined NIAB on 4th December, 2017.

Research experience and interests
Dr. Dey’s experience spans various aspects of research in Tuberculosis (TB) including, molecular basis of TB pathogenesis: host-pathogen interaction, immunology of TB and vaccine development and animal models of TB, TB latency and reactivation. He developed several genetically engineered recombinant vaccines, some of which imparted heightened protection among the experimental TB vaccines studied till date.

Dr. Dey’s group works on tuberculosis (TB) and other zoonotic bacterial diseases of livestock in the broad area of molecular pathogenesis, genetic diagnosis, engineered vaccines and therapies, especially- (a) identification of immunological and transcriptional biomarkers of susceptibility and/or resistance to TB in native and crossbred cattle, (b) development of inhibitors of a bacterial enzyme involved in biofilm formation and cell wall homeostasis to develop alternative antibacterial to limit antimicrobial resistance (AMR) and (C) development of engineered probiotics based novel prophylactic and therapeutic antimicrobial.
