So happy to share this! Bacteriocins were first discovered over 100 years ago, but what do they actually do? We look at >1000 bacteriocin plasmids and find links to virulence and antimicrobial resistance, and frequent bacteriocin sharing in Enterobacteriaceae.

Bacteria employ a range of competition systems that deliver toxins to inhibit competing strains. This study shows that these systems are particularly important for the ecology of virulent and antibiot...

Is it “winner-takes all” when the simplest living things compete? Check out my fresh publication on phage coexistence in Science and a thread below🧵 www.science.org/doi/10.1126/...
Diverse phage communities are maintained stably on a clonal bacterial host
Bacteriophages are the most abundant and phylogenetically diverse biological entities on Earth, yet the ecological mechanisms that sustain this extraordinary diversity remain unclear. In this study, w...

Wrapped up supervising a project on Tubeworm symbioses! Such a throwback to marine micro days. From sponges to mice, my academic journey keeps reinforcing my belief: the treasure lies in understanding ground-rules of host-microbe ecology & evolution applicable across host organisms.

I like to read *real* microbial ecology research periodically to remind me that opportunistic pathogens and model systems exhibit only a narrow range of possible interactions. For example, this makes our fascination with surface-sensing seem small:
