Sharing exciting work led by PhD students McCallum and Burckhardt! We created a new series of syn bio tools in Bacteroides to create non-invasive, real time and sensitive in vivo gut biosensors. www.biorxiv.org/content/10.1...
Expanding the Bacteroides synthetic biology toolkit to develop an in vivo intestinal malabsorption biosensor.
The human gut is a highly dynamic physical environment where perturbations - including factors such as acidification, oxygenation, and particle concentration (osmolality) - can influence microbiota co...

Excited to share our latest preprint led by Dr. Hunter! We show that osmotic shifts, common in the gut, alter T4 phage-E. coli evolution. High osmolality promotes fitness but selects for mucoid, weakly phage-resistant E. coli, with implications for phage therapy! biorxiv.org/content/10.1...
Osmotic conditions shape fitness gains and resistance mechanisms during E. coli and T4 phage co-evolution
Bacteriophages, or phages, are viruses that infect bacteria and offer a promising approach to combating antimicrobial resistance in the gut by selectively targeting harmful bacteria while preserving t...

Very excited to share a new paper in collaboration with the Ciernia lab! We show that early-life inflammation alters sex hormones and mating behavior in mice, alongside shifts in hormone-modifying microbiota members! Great work by Olivia Sullivan, Claire Sie and many others! doi.org/10.1016/j.bb...
