We use numerical models to study the interactions between life and environment on Earth and habitable exoplanets to inform life detection missions. Our research has three major themes:
Earth System Evolution
How have biology, ocean-atmosphere chemistry, the solid Earth, and climate co-evolved throughout our planet's history?
How do stellar, orbital, and planetary properties shape surface environments and influence long-term habitability?
How can we recognize the fingerprints of life in on exoplanets with current and upcoming telescopes?
