Healthy Infrastructure Research Group


Life in the 21st century is very different to how it used to be. More than half of the world's population is now living in cities and migration is higher than it has ever been. As a result, we come into contact with many more individuals in a single day then our ancestors did in a lifetime.

We also spend the majority of our time indoors. Confined environments are not always healthy and contact with many people can lead to the spread of infection. This situation has been made more difficult with worldwide travel which transfers infections across the globe and by the onset of antimicrobial resistance.

The Healthy Infrastructure Research Group studies how we can make our environment healthier and how to reduce the spread of infections by:
  1. Investigating how microbes behave and survive in indoor environments;
  2. Developing engineering solutions that improve environmental health;
  3. And testing antimicrobial strategies.

Listen to HIRG Director Dr Lena Ciric discuss HIRG's work for the Wellcome Collection Packed Lunch podcast.

Dr Lena Ciric and the HIRG team were featured in a recent Microbiology Society podcast explaining the science behind engineering the built environment to prevent infections.
