Léo Martire


Education: 
  • Dr. Léo Martire received his PhD degree with honours in Astrophysics, Space Science, and Planetary Science from the Institut Supérieur de l'Aéronautique et de l'Espace (ISAE-Supaéro, Toulouse, France, 2017-2020).
  • He obtained an MSc in Engineering from the Institut National des Sciences Appliquées (INSA, Toulouse, France, 2014-2017), and another MSc in Optimization from the Université Paul Sabatier (Toulouse, France, 2016-2017).

Research Interests: 
  • Atmospheric science, with a focus on mechanical waves and the mechanical coupling to the ground.
  • Numerical modeling and fluid mechanics.
  • Applications to planetary science, and especially Mars and Venus.
  • Geophysical monitoring from airborne barometers, application to Venus.
  • Multi-GNSS ionospheric sounding, application to a real-time tsunami early warning system.

Professional Experience: 

His doctoral dissertation featured both numerical modeling and experimental applications, researching topics in propagation of infrasound in coupled solid/fluid or ground/atmosphere systems. He analyzed terrestrial tropospheric and stratospheric datasets (i.e., seismic infrasound, microbaroms), demonstrated the presence of infrasound on Mars as measured by SEIS instrument onboard NASA’s InSight lander, and worked with Dr. Baptiste Chide on modelling acoustic attenuation for SuperCam’s microphone on board Mars2020 Perseverance. During prior internships, he developed N-bodies simulations at the European Southern Observatory (ESO) in order to numerically study the effect of gravitational shocks on globular star clusters, and helped the French Space Agency (CNES) design algorithms based on measure theory for orbital collision risk assessment
