Post-doc modelling landscape evolution and cosmogenic detrital signal in Toulouse
Geosciences Environnement Toulouse (GET), Joint Research Unit of CNRS, IRD, Toulouse 3 University and CNES, , France
Apply before: 21 April 2023

We are looking to recruit a post-doc for two years in the geomorphology group at GET in Toulouse, France. The post-doc will work in the framework of the PANTERA project funded by the French ANR, to model the evolution of the cosmogenic isotope detrital signal at the outlet of African catchments during Quaternary climate changes. Details are given below. Do not hesitate to contact me if you have any questions.

Best regards,

Sébastien Carretier

Subject: Numerical modelling and measurements of detrital cosmogenic signal variations in rivers for paleo-catchment mean erosion rates.

Employer: French CNRS (

Location: Geosciences Environment Toulouse (GET, Toulouse, France

In collaboration with: CRPG, Nancy, France (projet leader and CEREGE, Aix en Provence, France (

Supervision/team: S. Carretier (GET), V. Regard (GET), D. Rouby (GET), B. Plazolles (GET), S. Choy (GET), J. Charreau (CRPG), PH. Blard (CRPG), V. Godard (CEREGE), R. Braucher (CEREGE), I. Schimmelpfenning (CEREGE).

Required education: PhD in Earth sciences

Duration and timing: 2 years, starting in September 2023

Funding by: French ANR (, project PANTERA

How to apply: Please contact Sébastien Carretier ( with “PANTERA Postdoc application” in the subject line before 21 April. Include a CV with a short (1 page) research statement summarizing research experience. A short list will be established shortly after 21 April and candidates will be interviewed remotely then.

The impact of glacial and interglacial cycles on the denudation of continents during the Quaternary remains a debated topic. One of the challenges is to develop methods to quantify paleo-erosion rates from the concentration of cosmogenic isotopes in offshore sediment at river mouths. To identify the climate signal, it seems appropriate to study catchments located on cratons. However, sediment transport times and recycling in such catchments may bias the cosmogenic record of paleo-erosion rates. It is therefore necessary to assess these effects through numerical modelling coupling landscape dynamics and the tracking of cosmogenic isotope detrital signal in river sands. This is one of the approaches of the ANR PANTERA project (PI J. Charreau at CRPG) which aims to reconstruct Plio-Quaternary paleo-erosion rates from the cosmogenic signal in the offshore sediments of several African rivers. This project is a consortium between the CRPG in Nancy, the CEREGE in Aix en Provence, and the GET in Toulouse. The post-doc project includes the acquisition of cosmogenic isotope data and the modelling of the detrital signal in cosmogenic isotopes, which constitutes the main objective. This modelling will be carried out using the Landscape Evolution Model CIDRE, which couples the landscape evolution and the tracking of grains whose cosmogenic isotopes concentrations vary during transport. The main site of the post-doc will be at GET in Toulouse within the geomorphology group under the main supervision of S. Carretier. The post-doc will benefit from strong interactions with members of the geomorphology group and LOA team on related projects in Toulouse ( The work will be also carried out in collaboration with the other members of the project, at CRPG and CEREGE. The profile sought is a geomorphologist, ideally with skills in cosmogenic isotopes and modelling.
