Owen works on the theory and observational consequences of protoplanetary disk evolution, photoevaporation and exoplanet demographics, explaining features such as the observed radius gap in close-in exoplanets.

NON-PREFERRED (astronomy pivot, kept for review). Seager's group works on exoplanet atmosphere and interior characterization and the search for atmospheric biosignature gases, including leadership of space-mission concepts (Starshade, ASTERIA, TESS deputy science direction) that require high-contrast, high-resolution spectroscopic instrumentation; per public reporting she is departing MIT for the University of Toronto/CITA effective September 1, 2026, so any postdoc search should confirm her host institution directly.
