Sara Seager’s current research interests are focused upon the discovery and characterization of exoplanets. She has two main goals: the discovery of another Earth and the search for signs of life beyond Earth. Thousands of exoplanets are known to exist with exoplanet atmospheres now a firmly established field of research. Seager’s group aims to understand the atmospheric composition and the interior structure of small rocky exoplanets, of the kind with potential to host life.
