Particles physics, astrophysics, geosciences, environment and ecology (PAGE)

The universe: origin, composition, evolution / Earth and anthropization: climate, ecosystems, risks and resources.
This research department deals with pluridisciplinary research in the areas of particle physics, astrophysics, Earth and the universe, environment and ecology. It requires big infrastructures, long-term observations, and powerful computing tools (data, computing power). Coordination with a national strategy is therefore important to develop strong links with technology and instrumentation. PAGE regroups 14 laboratories, 244 researchers, 250 professors-researchers and 400 PhD students.

Strategic axis

The universe: origin, composition, evolution

Research fields: nuclear physics, particles physics, astroparticles, astrophysics, cosmology and planetology

Research units include: IPAG, LAPP, LAPTh, LPSC, LSM, with strong link to the Enigmass and Focus Labex projects.

Societal issues:
  • Reactor physics: which nuclear sectors for the future? Accelerator-driven reactors, thorium reactors
  • Medical physics: neutron capture therapy, hadrontherapy, X radiotherapy monitoring
Scientific challenges at stake:
  • to reproduce the first instants of the university in a laboratory environment
  • to explore the distant universe
  • to search for exoplanets
Synergies with the other Grenoble Alpes laboratories for a post-Labex strategy:
  • interactions with IPAG (astrophysics) LPSC, LAPP
  • interactions with theoretical scientistis (LAPTh) and with physicists and mathematicians of the PEM and MSTIC research departments
Specific needs in terms of computing power, storage capacity and data processing, as well as R&D transfer (instrumentation): adaptive optics, miniaturized spectro-imagery, sensors, interfermotry ion source, plasma, accelerator

Earth and anthropization: climate, ecosystems, risks, resources

Research fields: earth sciences, climate sciences, ecology and environment

Research units include: Isterre, LEGI, LGGE-LTHE (IGE), Edytem, LCME, Irstea EMGR & ETNA, LECA, CARRTEL, with strong links to the OSUG@2020 Labex project

Social challenges:
  • understanding and adapting human societies to global challenges
  • remediation measuresnatural and technological risks
The objectives are to rely on previous achievements realized in polar environments, mountainous areas, West Africa, etc, in order to:
  • improve the synergies between theory, observation and instrumentation
  • develop the spatial activity (instrumental research and signal processing)
  • co-construct projects about (geo-, hydro-, eco-, socio-)systems
Institutional challenges:       
  • achieve the LTHE-LGGE merger
  • improve the visibility of research in the areas of ecology and environment
  • identify synergies between research organizations and institutes (CNRS) for infrastructures allowing the observation of natural systems
