A global comparison of surface and subsurface microbiomes reveals large-scale biodiversity gradients, and a marine-terrestrial divide

Drew Steen

Associate Professor of Biological Sciences and Earth Sciences

We in the Steen Lab want to understand how microbes interact with organic matter in aquatic systems. To do that, I use the tools of organic geochemistry as well as microbial ecology. These questions have lead us to work on new approaches to analyze DNA sequences from environmental microbiomes and to study the distribution of taxa and functions across all of microbial life.
