We study gut bacteria and the immune response to infection with a focus on the danger signal extracellular ATP. We particularly like Shigella and E. coli. Located at Queen's University Belfast, UK and Umeå University, Sweden.

Our first effort exploring gut bacteria-extracellular ATP interactions is published! We show that eATP rewires gene expression and physiology in harmless and pathogenic bacteria, impacting production of bioactive metabolites, antimicrobial sensitivity, and virulence.

We had the pleasure to host Molly Ingersoll and Nassos @typaslab.bsky.social at the Fraser Symposium in Infection Biology 2025 at @qubelfastofficial.bsky.social . The day was a delight, except for the Belfast weather (don’t trust the photo!). Stay tuned for next year's symposium announcement!
