Dr. Koskinen’s research focuses on the structure and evolution of planet and satellite atmospheres in the Solar System and extrasolar planetary systems. He is particularly interested in the physics and chemistry of the middle and upper atmosphere that he studies with the analysis of observations and theoretical modeling. Tommi was a participating scientist on the Cassini mission and is still actively involved in researching the atmospheres of Saturn and Titan. He develops and maintains models of exoplanet atmospheres that are required to interpret current and planned observations as well as to simulate mass loss and address questions on long-term evolution. Dr. Koskinen was appointed as Assistant Professor at LPL in 2017.
