Dr Archana Madhav

Postdoctoral Fellow

Dr Archana Madhav leads a Wellcome Trust-funded collaboration with icddr,b which aims to investigate the relationship between the microbiome, infectious diseases, and climate. She promotes global partnerships to strengthen public health in low-resource settings to improve disease understanding and control through innovative genomics approaches.

I am a postdoctoral fellow and project lead from the Parasites and Microbes programme on a 3-year collaboration with the International Centre for Diarrhoeal Disease Research, Bangladesh (icddr,b). My current work focuses on developing genomic surveillance systems to track key pathogens in regions affected by climate change.

Prior to this, I completed my PhD at the University of Cambridge, where I first became a microbiome nerd when investigating antimicrobial resistance (AMR) in patients undergoing transplantation, with a focus on the gut as a reservoir for resistant pathogens. In collaboration with Christian Medical College, Vellore, I launched a prospective study using genomics to demonstrate, for the first time in India, that bloodstream infections following haematopoietic stem cell transplantation could originate from the gut.

At Sanger, I aim to continue applying advanced genomic tools to public health challenges and to build equitable, interdisciplinary research collaborations to generate context-specific, actionable data to inform infection control strategies. I am also committed to supporting global efforts in capacity building for genomic surveillance and ensuring that scientific advances benefit the regions that need them most.
