Title: Geomicrobiology Research Group

Group: Onstott Research Laboratory

Area(s): Geochemistry, Geomicrobiology

Research Summary: Tullis Onstott, a Princeton graduate and professor of geosciences known for his innovative research in several specialties and his explorations of lifeforms deep below the Earth’s surface, died Oct. 19, 2021, in Oracle, Arizona, from complications associated with lung cancer. Research Associate Renxing Liang and Grad Students Zachary K. Garvin and Devan M. Nisson maintain his research laboratory at Guyot Hall.

Tullis Onstott focused his research on subsurface microbial life. This research involves exploration of subsurface microbial ecosystems via mines, drilling, and new underground laboratories, and by quantifying their community structure, function, and activity. His group does this by analyzing metagenomes, metatranscriptomes and metaproteomes, performing stable isotope measurements, and combining geochemical measurements with thermodynamic models.
