Research Interests

Dr. Emilie Royer's research focuses on Ultraviolet (UV) spectroscopy, toward a better understanding of the interactions of diverse Solar System objects with their immediate environment. She uses UV wavelengths to study icy surfaces of airless bodies, as well as upper atmospheres. Research projects on upper atmospheres include the analysis of the Nitric Oxide (NO) nightglow at Venus and Mars, and the analysis of the Titan airglow. Research projects on icy surfaces include the analysis of the UV photometric and compositional properties of the icy satellites of Saturn: Mimas, Tethys, Dione, Enceladus and Rhea. Working toward the study of the origin and evolution of the system of Saturn, Dr. Royer is also the Principal Investigator of a multi-wavelength study (from the UV to the InfraRed) of the the satellite Dione and its co-orbital moon Helene.

Professional History

Dr. Royer obtained her Bachelor of Science in Earth Science from the Université de Bretagne Occidentale, Brest, France in 2005. In 2006, she obtained a Master of Science in Earth Science from the University of Nantes, France, followed in 2007 by a Master of Science in Planetary Science from the University Paris VI, France. She received her Ph.D. in Astronomy and Astrophysics in 2011 from the Uiversité Paris VI, Pierre et Marie Curie, Paris, France, where she studied the Nitric Oxide (NO) aeronomic emissions, observed in ultraviolet by the SPICAV/Venus Express instrument, using the stellar occultation mode. As a postdoctoral scholar at Caltech-JPL, in 2012-2013, Dr. Royer's gained valuable experience investigating the photometric properties of the icy satellite of Saturn. Since, 2013 and prior to join PSI in 2019, she worked as a Research Scientist at the Laboratoty for Atmospheric and Sapce Physics (LASP), at the University of Colorado-Boulder, as part of the Cassini-UVIS team, working on icy satellites surfaces and airglow processes at Titan. Her work on airglow also led her to be part of MAVEN Science team to analyze NO emission in the upper atmosphere of Mars. At PSI, she is pursuing her research interests in both, icy surfaces and upper atmospheres, by contunuing her work on the Cassini and MAVEN datasets.

On the teaching side, Dr. Royer worked as a Geoscientist and Assistant Curator at the Palais de la découverte (a Science museum) in Paris from 2008 to 2012, where she gave lectures on plate tectonics, seismology, meteorology and climatology. She is an instructor at the University of Colorado-Boulder in the Astronomy and Planetary Science department.

Dr. Royer is currently serving as a member of the Venus Exploration Analysis Group (VEXAG), which has for mission to identify scientific priorities and future opportunities for the exploration of Venus and provide those findings to NASA Headquarters.
