About me

I'm a research engineer at the Observatoire des Sciences de l'Univers Nantes Atlantique (FR). I'm currently in charge to support and promote the french open-science initiative to open the research data and source codes from the observatory and its partners.

Previously, I worked at the Laboratory of Planetary and Geosciences in Nantes (FR) where I developed an open-source coverage analysis tool for the European Space Agency (ESA) to improve the observation planning of the Juice mission.

I also worked as a postdoc in the Planetary and Exoplanetary Atmospheres group at NASA/JPL. I analyzed the Titan's surface and atmosphere with the remote sensing instruments onboard Cassini (VIMS and ISS) and I studied new lossy data compression for outer-planetary missions.

In 2018, I developed the Cassini-VIMS data portal containing all Saturn's icy moons calibrated data and the PyVIMS python module.

I completed my PhD in Astrophysics in 2017 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.

Main open-source contributions


Python toolbox to perform surface coverage analysis based on orbital trajectory calculations.


Python library to manipulate the Cassini-VIMS hyperspectral cubes.

Python WebGeoCalc

Wrapper on top of NAIF WebGeoCalc API.


Wrapper on top of OPUS-SETI API.

As of July 2023, I contributed to 19 peer-reviewed publications including 5 papers as first or second author. I also frequently present my results in international conferences in Europe and the United States. A complete list of my publications can be found there:
