About the research centre or Inria department
The Inria Centre at Rennes University is one of Inria's eight centres and has more than thirty research teams. The Inria Centre is a major and recognized player in the field of digital sciences. It is at the heart of a rich R&D and innovation ecosystem: highly innovative PMEs, large industrial groups, competitiveness clusters, research and higher education players, laboratories of excellence, technological research institute, etc.
Context
Type: Research engineer position
Place: Inria Center of University of Rennes in the team-project COMPACT
Duration: 9 months
Collaboration during the project:
- Collaboration with Anne-Cécile Orgerie (Magelan team at IRISA)
- Collaboration with the GIS Marsouin (Human and Social Sciences)
Assignment
Context: Working towards a responsible and resilient digital future naturally means questioning a priori the relevance of any rising technology. But what about existing technologies? Trying to make them less energy-intensive proves insufficient, because of the rebound effect this implies. So we need to define limits for their use.
Goal of the project: In this project, we will explore the conditions for setting such limits, particularly in the case of video streams (which account for a significant proportion of CO2 emissions from the digital world). More specifically, we will study the levers (technical, regulatory, legislative, etc.) that can be put in place, as well as their effectiveness and acceptance by citizens.
This inter-disciplinary question will be addressed in close collaboration with researchers in the Human and Social Sciences.
