Deciphering the mineral clues to ancient life


We investigate the history of environments and life on Earth by looking at the activity of organisms and their mineral record.  As the diverse metabolisms of microbial life alter the surrounding geochemistry, organisms are leaving enigmatic clues of their presence — but how can we identify and interpret the record of life and its impact on the environment?


In the Microbe-Mineral Lab at U-Michigan, we examine ancient sedimentary rocks and modern mineralizing microbes using multi-faceted approaches to probe the biogeochemical record of the Precambrian Earth.

Welcome Kendall!

We had a belated welcome and birthday celebration for Kendall, who is now an undergrad researcher in the Microbe-Mineral Lab!  

Recruiting PhD Students for Fall 2019

I’m recruiting PhD students for Fall 2019 interested in understanding deep-time geobiology/ astrobiology and the evolution of metabolisms, through microbe-mineral lab experiments and mineral characterization! We have multiple projects recreating BIFs in the lab and constraining ancient seawater chemistry — […]

Welcome Sammy and Isaac!
