🚨New preprint from our lab!🚨
We trace the evolution of microbial exoenzymes and uncover their role in Earth’s oxygenation. By recycling nutrients, exoenzymes helped fuel cyanobacteria and set off feedbacks that sustained the long-term rise of O₂.

Hey are you looking for a postdoc focusing on microbial
ecology/bioinformatics? Hit me up - it’s not my lab but trying to help someone else staff their lab. If you have a student about to defend, this could be a great chance to get a ton of papers.
