How can we learn about the organisms that live underground based on the organic molecules and minerals that they make?
What sets the hydrogen isotopic composition of organic matter and how does that vary between microbial communities?
This is a collaborative project with Yarrow Axford where we reconstruct paleoclimate of Greenland during the Holocene and beyond.
How do they form in the modern and what environmental signatures do they preserve in the ancient?
Using geochemical and genomic insights to cultivate classically uncultivable microorganisms.
Be it in a hot spring, a cave, or saline microbial mat, how do microbes adapt to, and change, their environments?
