Bethany Theiling PhD

Assistant Professor of Geosciences College of Engineering & Natural Sciences


Bethany Theiling's research focuses on applying geochemical analytical techniques to questions spanning from astrobiology to paleoclimatology. One of her research projects investigates the chemical biosignatures of possible microorganisms on Europa. Another of her research projects seeks to characterize the effect of land plant evolution on oceanic nutrient flux, oceanic anoxic events, and marine biotic events.
