Curriculum Vitae:

Anthony Lethuillier-Letoquin

Anthony is a post-doctoral researcher in the Planetary And Exoplanetary Atmospheres group at JPL where he is currently working on analyzing the data of the MIRO/Rosetta instrument to try to understand the subsurface properties of the 67P/C-G comet. Throughout his PhD, as CO-I of the PP-SESAME/Rosetta permittivity probe instrument, he worked on constraining the physical properties of the final landing site of the Philae probe. Finally, he also worked on a reanalysis of the results of the PWA-HASI instrument with the help of numerical simulations and laboratory measurements of analogs. Anthony has a special interest in scientific outreach most notably volunteering on the French National Day of Science and helping to organize the Elbereth conference held at the Paris Astrophysics Institute.

  • PhD Astronomy & Astrophysics, LATMOS, France, 2016
  • Masters in Planetology, Université Paris-Sud, France, 2013

Research Interests
  • Origins and evolution of the Solar System
  • Subsurface properties of planetary objects
  • Laboratory dielectric spectroscopy of materials relevant to planetary exploration
  • Space instrumentation (mutual impedance probes, microwave radiometers, radars)


Rosetta Icon Rosetta
The Rosetta mission is designed to study the origin of comets, the relationship between cometary and interstellar material and its implications with regard to the origin of the Solar System.

MIRO (Microwave Instrument for the Rosetta Orbiter) is a scientific instrument on the ROSETTA Spacecraft.
