Josh Winn's research goals are to explore the properties of planets around other stars, understand how planets form and evolve, and make progress on the age-old question of whether there are other planets capable of supporting life. His group uses optical and infrared telescopes to study exoplanetary systems, especially those in which the star and planet eclipse one another. He was a Participating Scientist in the NASA Kepler team and is a Co-Investigator and Architect of the ongoing Transiting Exoplanet Survey Satellite mission. Over the years, he and his group have also pursued topics in stellar astronomy, tidal evolution, planetary dynamics, radio interferometry, gravitational lensing, and photonic bandgap materials.
