A propos du centre ou de la direction fonctionnelle

The Inria Lille - Nord Europe Research Centre was founded in 2008 and employs a staff of 360, including 300 scientists working in fifteen research teams. Recognised for its outstanding contribution to the socio-economic development of the Hauts-De-France région, the Inria Lille - Nord Europe Research Centre undertakes research in the field of computer science in collaboration with a range of academic, institutional and industrial partners.

The strategy of the Centre is to develop an internationally renowned centre of excellence with a significant impact on the City of Lille and its surrounding area. It works to achieve this by pursuing a range of ambitious research projects in such fields of computer science as the intelligence of data and adaptive software systems. Building on the synergies between research and industry, Inria is a major contributor to skills and technology transfer in the field of computer science.

Contexte et atouts du poste

This PhD student position will be supported by the HE Trumpet project

While AI techniques are becoming ever more powerful, there is a growing concern about potential risks and abuses. As a result, there has been an increasing interest in research directions such as privacy-preserving machine learning, explainable machine learning, fairness and data protection legislation.
Privacy-preserving machine learning aims at learning (and publishing or applying) a model from data while the data is not revealed. Notions such as (local) differential privacy and its generalizations allow to bound the amount of information revealed.

The overall goal of the TRUMPET project is to research and develop novel privacy enhancement methods for Federated Learning, and to deliver a highly scalable Federated AI service platform for researchers, that will enable AI-powered studies of siloed, multi-site, cross-domain, cross-border European datasets with privacy guarantees that exceed the requirements of GDPR. 

INRIA's MAGNET team will contribute among others to tasks involving AI algorithms and architectures, federated Learning, privacy platforms, privacy measurement and metrics, privacy-enhancing technologies and applied cryptography


Mission confiée

The recruited PhD student will collaborate with colleagues in the MAGNET team and the TRUMPET project consortium in general.  Part of the work may involve travel to other partners.

If the research features a prototype, it will contribute to the project's open source library and may be supported by engineers in the team.

Possible topics of research include (but are not limited to):

  • Cryptography-based strategies to improve the security of privacy-preserving AI systems.
  • Inference methods for privacy assessment
  • Design and development of the TRUMPET platform and its supporting algorithms


Principales activités

  • Contribute to the research of the TRUMPET project
  • Collaborate with other MAGNET and TRUMPET team members
  • Disseminate research results



The ideal candidate will have the following skills:

  • Good mastery of English
  • A strong background in computer science and mathematics.  Subject matters which will be needed during the research include (but are not limited to) machine learning, statistics, cryptography, distributed systems, constraint programming.
  • Good programming skills (e.g., C/C++ or python) and supporting tools.
  • Relational skills, e.g., working in a team, effective reporting and communication with all involved stakeholders.


  • Subsidized meals
  • Partial reimbursement of public transport costs
  • Leave: 7 weeks of annual leave + 10 extra days off due to RTT (statutory reduction in working hours) + possibility of exceptional leave (sick children, moving home, etc.)
