Doctoral dissertation exploring testing the silicate-weathering feedback, detectability of biosignatures, and the climate behavior of tidally locked planets; includes statistical approaches and 3D model studies tailored to future direct-imaging missions.

Uses a coupled ocean-atmosphere GCM (ROCKE-3D) to show that inclusion of ocean heat transport does not reintroduce the Snowball bifurcation for tidally locked planets; suggests such planets are unlikely to stay in global glaciation for geologically significant timescales.

White paper / preprint proposing statistical methods to extract habitability signals from ensembles of exoplanet observations to guide future mission planning.

Demonstrates that tidally locked planets (common around M-stars) do not exhibit the abrupt Snowball bifurcation seen on rapidly rotating planets, with implications for habitability and long-term climate behavior.
