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 EvolutionHow have biology, ocean-atmosphere chemistry, the solid Earth, and climate co-evolved throughout our planet's history?
|
Planetary HabitabilityHow do stellar, planetary, and biological properties influence long-term habitability?
|
Exoplanet BiosignaturesHow can we recognize the fingerprints of life in observations of exoplanet atmospheres with upcoming space-based telescopes?
