About the research centre or Inria department

The Inria research centre in Lyon is the 9th Inria research centre, formally created in January 2022. It brings together approximately 300 people in 16 research teams and research support services.

Its staff are distributed at this stage on 2 campuses: in Villeurbanne La Doua (Centre / INSA Lyon / UCBL) on the one hand, and Lyon Gerland (ENS de Lyon) on the other.

The Lyon centre is active in the fields of software, distributed and high- performance computing, embedded systems, quantum computing and privacy in the digital world, but also in digital health and computational biology.


Wireless communication systems involve collecting large amounts of data related to electromagnetic propagation, which is normally used for the purpose of data transmission and demodulation, and then immediately discarded. While it is clear that leveraging the statistical aspects of propagation information (e.g. through learning the characteristics of its distribution and applying appropriate statistical techniques) has the potential to greatly enhance the performance and range of services offered by the network, this approach faces the practical challenges of real-time processing such as a limited computing and storage resources.


The successful candidate will contribute to the development of advanced machine learning approaches for the processing of real-time signals in wireless communications systems, and in particular of the technique of channel charting FGST23. She or he will devise innovative theoretical approaches for distributed, real-time dimensionality reduction applied to multi-sensor systems; prototype these approaches trough simulations and/or lab experiments; write technical reports and articles for major conferences and journals in the field of wireless communications and machine learning; and regularly present the obtained results in scientific conferences and events.

The proposed topic lies at the crossroads of unsupervised machine learning, frugal AI, and signal processing for digital communications. It can lead to a number of directions ranging from theoretical machine learning to real-time implementation, depending on the skills and preferences of the candidate.

Main activities

The successful candidate will join the MARACAS research team of Inria (https: //, hosted by CITI Lab (https: // www. citi- in Lyon, France. MARACAS is a research group consisting of approximately 15 people within Inria and INSA Lyon. The focus of MARACAS lies in the theoretical, algorithmic and experimental aspects of communication systems, developing and applying methods in information theory, statistical signal processing and machine learning.

The offered post-doctoral contract is for a fixed-term 18 months position funded by a collaborative research project. The candidate will have the opportunity to interact and collaborate with our high-profile partners from various European universities involved in the collaborative project funding the work. The candidate will be supervised by Dr. Maxime Guillaud.


The candidate must hold a PhD degree (or must be about to obtain a PhD) in a relevant field such as: computer science, informatics, electronics, mathematics, or statistics.

Required skills:

  • fluent spoken and written technical english
  • a strong background in machine learning, digital communications, statistical signal processing and/or information theory
  • a solid publication track record
  • familiarity with ScikitLearn, TensorFlow or Keras
  • Benefits package
