About Me

I am an Associate Professor at IMT Atlantique (formerly Telecom Bretagne), one of the top French technical universities, located in Brest, France. I am also affiliated with the Lab-STICC research laboratory, where I currently lead the CODES team. I am interested in channel coding: how to make our digital communication and storage systems more resilient to errors and failures. I am also working on digital signal processing algorithms to enable emerging space optical communication systems. Over the past few years, I have developed a strong interest in deep learning and its applications to communications systems. More recently, I have been exploring how AI, LLMs and agents in particular, can be leveraged to accelerate research and transform engineering education.

We’re always looking forward to working with motivated students and researchers. Please check out regularly the Lab-STICC and IMT Atlantique job offers for new PhD and post-doctoral opportunities in our team, or feel free to send me an email.

My Research

My core research activity focuses on designing waveforms and algorithms for reliable and efficient digital communications. It revolves around three main areas of expertise: channel coding, signal processing for digital receivers, and more recently deep learning.

A central part of my research is devoted to designing new error-correcting codes and decoders for emerging digital transmission and storage systems. From 2021 to 2025 I led the AI4CODE project that explored how deep learning can help design better error-correcting codes and decode them more efficiently. I am also genuinely curious about unconventional applications of coding theory beyond telecommunications, for instance in molecular biology.

I am currently working with CNES, Safran Data Systems and Thales Alenia Space on the design of coherent systems and modems for LEO and GEO ground-to-satellite optical links. A major challenge is to compensate for the atmospheric disturbances experienced by the optical wave as it travels through the atmosphere, within the processing constraints afforded by the hardware and imposed by the high data rate.

Previously I developed DSP algorithms for fiber optical transport and access networks in close collaboration with Orange (photo from the trenches). Before that, I explored iterative equalization and decoding in wireless systems, at the golden age of turbo codes and iterative information processing.

I must confess I now spend an embarrassing amount of time talking to my computer.

I got hooked on evolutionary coding agents and how to use them to discover new algorithms in an automated way. I am particularly interested in making these models collectively more creative and efficient in their research.

Full publications record available in my CV and on my Google Scholar.
