Tullis C. Onstott

Tullis C. Onstott of Princeton University, Department of Geosciences, investigates the activity and survival of bacteria and other microorganisms in the deep subsurface (> 0.5 km) and their impact on the geochemistry and mineralogy of deep Earth.

The research questions that his group attempts to address include:

  1. Do subsurface microorganisms evolve by adaptation, selection or horizontal gene transfer?
  2. What constrains the diversity and density of subsurface life?
  3. What role does radiation play as an energy source for life?
  4. Could life have originated in the subsurface?
  5. What methods can be adapted to test for life in the Martian subsurface?

Onstott will present two talks during his visit:

The talks are co-sponsored by the OSU College of Earth, Ocean, and Atmospheric Sciences, and the OSU Research Office.
