We’re back at the Stanford synchrotron, and getting to try out our new liquid nitrogen dewar where we’ve stored our samples en route to keep them pristine and unaltered. Already getting some ‘illuminating’ iron X-ray spectra of Isaac’s experimental precipitates!

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 — including field work, multi-technique characterization, and anoxic glovebox work. Come join us! Please contact…
Welcome Sammy and Isaac!
The first Microbe-Mineral lab happy hour took place today (Aug 15, 2018) to welcome Isaac to Michigan and welcome Sammy to the lab!
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 by reduced iron, challenging current hypotheses for BIF formation centered on iron oxides.
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!
