Curriculum Vitae:

Benoit Seignovert

I’m a post-doctoral researcher in the Planetary and Exoplanetary Atmospheres group at JPL. I’m currently working on analyzing the Cassini data of Titan’s atmosphere to characterize the evolution of its clouds and haze content in order to improve our understanding of exoplanets’ atmospheres. Before coming to JPL, I worked at the University of Nantes (FR) to develop a web-portal to share the Cassini-VIMS calibrated data with external researchers and the general public.

In 2017, I completed my PhD in Astrophysics at the University of Reims (FR) where I developed radiative transfer models to analyze the detached haze layers observed by Cassini-ISS instrument at high altitude in Titan’s upper atmosphere.

Finally, during my Master degree in Planetary Science, I had the opportunity to work on geo-signatures of Titan’s lakes, evaporates, dunes and yardangs observed by Cassini VIMS and RADAR instruments.
