I am currently a NASA Postdoctoral Program Fellow at the Goddard Space Flight Center. After completing my Ph.D. at the Institut d'Astrophysique de Paris, France, I spent one year at the University Pierre & Marie Curie (Paris VI) as a Postdoctoral Research Associate, dividing my time between research and teaching.

Brief Bio
Teaching Experience
I taught an amount of 329 hours at the University Pierre & Marie Curie (Paris 6). It includes courses in physics and astrophysics at undergraduate and Master 1 levels, supervision of practical works, and oral examinations. I taught also 54 hours at the Hospital La Pitié-Salpêtrière in Paris, thermostatistics and nuclear physics applied to cancer treatments. Before my Ph.D., I was examiner in the French "Classes Préparatoires aux Grandes Écoles" for the French Ministry of Higher Education and Research. I was also a tutor at the École Normale Supérieure in Lyon from 2009 to 2011, and a full time teacher in high school
during 3 months in 2009. I have been a mentor of many students.

NASA's Spitzer: a second eye to detect planets deep within the Milky Way
May 2015 - May 2015
I have been invited to the radio program "La Tête au Carré" at the French national radio "France Inter" to comment the very exciting first measurement of a parallax effect in a planetary microlensing event (OGLE-2014-BLG-124). The detected planet is 13,000 light-years away from Earth. It is one of the farthest know exoplanet in our Galaxy.
