Research &
Surveillance

To prevent infections, our multidisciplinary team monitors where diseases are spreading, and investigate to understand how and why. Our work covers a range of topics, all aiming to promote and implement better healthcare in Bangladesh and worldwide.

Genomics

We learn more about microorganisms by looking at the molecular level to understand how they work.

Antimicrobial Resistance (AMR)

Increasing resistance of bacteria to antibiotics is one of the world’s biggest concerns, we monitor AMR and also seek novel antimicrobials.

Demographic Surveillance

Not all children who fall sick visit the hospital, so we look to the community as well to truly understand child health.
