Scientist, Planetary & Exoplanetary Atmospheres
NASA Exoplanet Exploration Program
Pin Chen collaborates with Scott in developing the AROC (Atmosphere-Rock-Ocean Chemistry) model to investigate potential biosignatures. This model integrates atmospheric photochemistry and equilibrium aqueous chemistry to model coupled atmosphere-hydrosphere-lithosphere chemistry. We envisage AROC representing the “planetary reactor,” which chemically processes biogenic gases to produce changes in atmospheric composition. We aim to identify detectable atmospheric spectral signatures that potentially indicate habitability and/or life
