**Type de contrat**: CDD

**Contrat renouvelable**: Oui

**Niveau de diplôme exigé**: Thèse ou équivalent

**Fonction**: Post-Doctorant

**A propos du centre ou de la direction fonctionnelle**:
Created in 2008, the Inria center at the University of Lille employs 360 people, including 305 scientists in 15 research teams. Recognized for its strong involvement in the socio-economic development of the Hauts-De-France region, the Inria center at the University of Lille maintains a close relationship with large companies and SMEs. By fostering synergies between researchers and industry, Inria contributes to the transfer of skills and expertise in the field of digital technologies, and provides access to the best of European and international research for the benefit of innovation and businesses, particularly in the region.

For over 10 years, the Inria center at the University of Lille has been at the heart of Lille's university and scientific ecosystem, as well as at the heart of Frenchtech, with a technology showroom based on avenue de Bretagne in Lille, on the EuraTechnologies site of economic excellence dedicated to information and communication technologies (ICT).

**Contexte et atouts du poste**:
This position is situated within the framework of the TROMAT (TRactable stochastic Optimization through MAtrix Theory) project, a public-academic initiative with significant industrial collaboration.

The project is funded by the Gaspard Monge Program for Optimization (PGMO), a program launched by EDF (Électricité de France) and the Jacques Hadamard Mathematical Foundation (FMJH) to foster collaboration between academic and industrial researchers on major challenges in energy and complex systems. The research is specifically supported under the PGMO's IROE sub-program, which focuses on disciplinary approaches to optimization and operations research. This context ensures that the project's outcomes are both scientifically innovative and practically relevant.

The work will be carried out through an international collaboration between two leading research teams: the INOCS (Integrated Optimization with Complex Structure) team at Inria Lille - Nord Europe, France, and the Continuous Optimization Team at the RIKEN Center for Advanced Intelligence Project (AIP) in Tokyo, Japan. The postdoc will be hosted at the Inria center in Lille, joining the INOCS team, which specializes in developing new models and algorithms for optimization problems with complex structures, particularly in the energy sector and supply chain management. The project also involves a close partnership with researchers from EDF R&D, providing direct insight into the real-world challenges that motivate the research and a clear path for technology transfer and impact.

**Mission confiée**:
**Assignments**:
The work will begin with a first phase, as outlined in the project's timeline. This includes conducting a comprehensive literature review to classify existing scenario clustering techniques within our proposed matrix framework, generating a diverse portfolio of test instances relevant to the energy sector (especially those of interest to EDF), and developing a robust, modular codebase for experimentation. Following this initial period, the postdoctoral researcher will take a leading role in driving the research forward along one of the project's primary axes: either developing a unified mathematical framework for clustering methods or exploring the use of numerical linear algebra techniques to construct computationally efficient model approximations.

**Collaboration**:
The recruited person will be based at the Inria Lille - Nord Europe research center (Villeneuve-d'Ascq, France) and will be an active member of the INOCS research team. This project is a close international collaboration. The recruited person will be in connection with Dr. Pierre-Louis Poirion from the RIKEN Center for Advanced Intelligence Project in Tokyo, Japan, and Dr. Wim van Ackooij, a senior researcher at EDF R&D. This collaboration will involve regular virtual meetings to discuss progress and a one-month research visit to Tokyo to work directly with Dr. Poirion on the matrix-based and linear algebra aspects of the project. The collaboration with Dr. van Ackooij will ensure the research remains grounded in and relevant to practical challenges in the energy sector.

**Responsibilities**:
The person recruited is responsible for conducting the day-to-day research activities of the project. This includes the theoretical development, software implementation, design and execution of computational experiments, and rigorous analysis of the results. The postdoctoral researcher will be expected to work with a high degree of autonomy and will take initiatives for shaping the project's scientific direction in collaboration with the principal investigators. A key responsibility will be to lead the dissemination of research findings, which i
