From Ben Good: competition btwn linked mutations can..enhance selection for modifiers that increase benefits of future mutations, even when they impose a strong direct cost on fitness. However..modest direct benefits can..drive evolutionary dead ends to fixation. www.nature.com/articles/s41...

Evolvability modifier mutations alter the rates and benefits of future mutations, but it is difficult to predict when they will be favoured by natural selection. A mathematical framework shows that co...

Paradoxically, preventing infection with high ABX can make patients susceptible to subsequent infections like C diff as gut flora get wiped out. Developing ABX that act in concert with the commensal microbiome to resist pathogens is a triumph www.nature.com/articles/s41...

Firmicutes appear to harbor host-specificity genes that allow them to bind to particular physical niches in the host gut I got to play a very minor role in this amazing work, and I'm so excited to see it out www.biorxiv.org/content/10.1...

My first theory project! I've really enjoyed how we could decompose complex dynamics into those of individual lineages. This approach is quite flexible, and we're hoping to extend it to more complex scenarios, including N(t) and certain forms of positive selection!
