Dr. Léo Martire

Dr. Léo Martire is a JPL Research Technologist in the Ionospheric and Atmospheric Remote Sensing Group, and the Deputy Director for the International GNSS Service’s Central Bureau since July 2022. They received their PhD degree with honours in Astrophysics, Space Science, and Planetary Science from the Institut Supérieur de l'Aéronautique et de l'Espace in 2020. They then joined JPL as a Postdoctoral Scholar, from February 2021 to July 2022.


Education: 

Research Interests: 
  • Multi-GNSS ionospheric monitoring. Computation of high-resolution global ionospheric maps. Development of a real-time GNSS-based early warning system for natural hazards.
  • Geophysical acoustics: atmospheric science with a focus on mechanical waves, and the mechanical coupling with the ground or the ocean surface.
  • Numerical modeling and fluid mechanics.
  • Applications to planetary science, and especially Mars and Venus.

Professional Experience: 

Their doctoral dissertation featured both numerical modeling and experimental applications, researching topics in propagation of infrasound in coupled solid/fluid or ground/atmosphere systems. They 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, they 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


Selected Awards:

  • ION GNSS+ 2022 Best Presentation Award (GUARDIAN: A Near Real-Time Ionospheric Monitoring System for Natural Hazards Early Warnings)
  • JPL Team Award 2021: Balloon-Based Acoustic Seismology Study (For conducting the first balloon-based seismology campaign with infrasound instrument design.)
  • Fondation ISAE-SUPAERO’s PhD Thesis Award (2020)
