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.

Isaac Successfully Defends Senior Honors Thesis!

Congratulations Isaac!

New Paper on BIF formation!

  Our paper was accepted at GRL and is online now! We determined the mineralogy and iron redox chemistry of nanoscale inclusions from 2.5 billion-year-old Banded Iron Formations (BIFs) and found that the primary minerals were iron-rich silicate minerals dominated […]

Isaac and Jena at SSRL

        Feb 7-9, 2018: Isaac and Jena traveled to the Stanford Synchrotron Radiation Lightsource (SSRL) to analyze Isaac’s experimental precipitates for his senior thesis. These analyses culminate many months of Isaac’s careful planning and hard work!
