On March 4, 2025, Lorenzo Ortega brilliantly defended his Habilitation à Diriger les Recherches (HDR) in front of a jury that praised the richness and level of his work: from left to right in the photo, Patrick DANES, Professor at Paul Sabatier University in Toulouse, Eric CHAUMETTE, Professor at ISAE-SUPAERO, Cédric RICHARD, Professor at Côte d’Azur University, Audrey GIREMUS, Professor at Bordeaux University, Lorenzo ORTEGA (our new HDR), Jean-Yves TOURNERET, Professor at Toulouse-INP and Nabil EL KORSO, Professor at Paris-Saclay University.

Congratulations Lorenzo for this great defense! A great career is coming for you … and for all those who are lucky enough to work with you 🙂

Corentin Lubeigt, postdoctoral fellow at Météo-France and former TéSA doctoral student, came to present an overview and perspectives on weather radars. While his PhD thesis focused on the study of GNSS signals reflected on the ground surface (see picture), he has now turned to weather applications to apply signal processing tools to weather radars. His research topics mainly focus on the analysis and improvement of estimator performance with applications in Earth observation and physical phenomena.

Willing to do a PhD? Interested by Space? Join us!

BEFORE March 14, apply online for TéSA thesis subjects at CNES! Seven topics are proposed:

• Protocols and RL Optimization for Nanosatellite Swarm Networks ;
• Optimizing Image Streaming via Dedicated Satellite Constellation Network ;
• Registration of Satellite Images by Spatial Contextualisation ;
• Detection / Localisation of Target Based on GNSS Reflectometry Processing ;
• Bias-Bounded Estimation of Phase Ambiguity for Precise Swarm positioning ;
• Machine Learning for Instrument Parameter Estimation ;
• Quantitative Forest Loss Monitoring using the BIOMASS Mission.

But before applying, do not hesitate to contact the PhD advisor mentioned or the director of TéSA (corinne.mailhes at tesa.prd.fr) for more information.

Colin Cros, postdoctoral fellow at ISAE-SUPAERO came to talk to us about cooperative positioning algorithms… a subject so fascinating that we forgot to take the traditional picture! This subject was at the heart of his PhD thesis work carried out at GIPSA-Lab in Grenoble, under the supervision of Pierre-Olivier Amblard and Christophe Prieur and financed by TELESPAZIO.
