About

Keivan G. Stassun is a leading astrophysicist whose research spans exoplanet detection, stellar astrophysics, and the development of innovative astronomical instrumentation. He is perhaps best known for his foundational work on the Transiting Exoplanet Survey Satellite (TESS), where he serves as a key science team member, and for his leadership in the SDSS-III MARVELS survey. Stassun’s major contributions include pioneering methods to characterize exoplanet host stars with unprecedented precision, directly improving the accuracy of planet radii and masses. His highly cited work on spectroscopic binary multiplicity, leveraging Robo-AO adaptive optics imaging (14 citations), has reshaped our understanding of stellar companionship and its impact on planet formation. He also led the development of DEMONEXT (8 citations), a low-cost, robotic telescope dedicated to exoplanet transit follow-up and transient events, demonstrating his commitment to accessible, automated astronomy. With over 400 publications and more than 20,000 citations, Stassun’s impact is immense. He is a Fellow of the American Association for the Advancement of Science and a recipient of the Vanderbilt University Chancellor’s Award for Research, reflecting his dual legacy as a brilliant scientist and a dedicated mentor.
