Job Opportunities: Research Positions at Le Laboratoire des Sciences du Climat et de l’Environnement (LSCE)

Seven Research Positions in “Modelling key vulnerabilities of terrestrial carbon stocks under climate change” at Le Laboratoire des Sciences du Climat et de l’Environnement (LSCE) in Saint-Aubin, France

LSCE are seeking seven enthusiastic and highly motivated candidates to work on new
representation of carbon loss pathways, leveraging novel observations, theoretical
understanding, machine learning tools and integration of processes with land surface
models. The topics range from modelling microbial carbon use efficiency, extreme fires,
permafrost collapse, and nutrient constraints on tree-based carbon dioxide removal, and
near-real time model predictions.


The amount of biological C stored in organic form on Earth is nearly 4,250 GtC. Destabilizing
only 10% of this carbon storage would be equivalent to more than 40 years of current
anthropogenic CO2 emissions. Despite this, biological carbon loss and mortality processes
are major gaps in our current knowledge of the carbon cycle, which have been ignored or
oversimplified in climate models, failing to reproduce the observed complexity of living
systems. These issues propagate to assessment of land-based climate mitigation measures
like afforestation or biomass plantations, and forecasting of near-real time greenhouse gas

The work:

The successful candidates will develop & apply the land surface model ORCHIDEE in
combination with unique observational dataset and novel machine learning tools within the
following international projects CALIPSO funded by Schmidt Futures (starting) and
coordinated by LSCE, RESCUE funded by the EU, and the RECCAP2-NRT project of the European Space Agency. Our international collaborators help to facilitate the assimilation of advances in observation, ecological theory and software engineering. The work will be guided & supported by senior scientists and software engineers at the LSCE.


  • PhD degree in environmental sciences, applied mathematics, computer
  • science or equivalent
  • Strong interest in numerical modelling and issues related to carbon cycling
  • and global change
  • Proficient in written and spoken English
  • Experience in programming (python, Fortran, R, etc)


  • Exciting and challenging tasks in an open, friendly and multicultural team
  • Excellent scientific infrastructure and research network
  • Training & support from Cambridge’s Institute of Computing for Climate Science
