About my group

Current members

Elie Dantziger – PhD candidate

Elie conducts ethnographic research in ecology laboratories. He focuses on projects that reconstruct ecosystems in closed and controlled environments. 

The PhD is supervised by Perig Pitrou (social anthropology) and Régis Ferrière (ecology)

Gaspard Demorcy – PhD candidate

In his thesis,  Gaspard uses a floating evaporation tank to combine multiple methods of direct measurement based on water balance and energy balance in order to directly measure evaporation in lakes.

The PhD is co supervised by Florence Habets (LG ENS)

Anne-Flore Didelot – PhD candidate

The thesis project aims to characterize the agronomic determinants of dissolved carbon, nitrogen, and phosphorus flows from agricultural soils into aquatic environments and the storage of carbon in soil mineral horizons. The goal is to contribute to the evaluation of new agricultural production systems, including methanisation-based products.

The PhD is supervised by Anne Jaffrezic (SAS, Rennes) and Emilie Jardé (Géosciences Rennes)

Ivy Notterpek – PhD candidate

Ivy’s thesis tests numerous biochemical approaches for recovering and characterizing combustion-related organic wastes. Fire-related activities and their development are studied in numerous Palaeolithic sequences from a diachronic perspective.

The PhD is supervised by Isabelle Thery (CNRS CPAM Nice)

Zoé Ott – PhD candidate

Zoé is working in the frame of the nutrilift project, which focuses on the importance of deep rooting in tropical agro ecosystems. She studies particularlry the root derived carbon in deep soil layers and its interactions witk organic and inorganic carbon.

The PhD is co supervised by Jean Riotte (IRD GET Toulouse). 

 Baptiste Hulin – PhD candidate

Baptiste’s thesis deals with root derived carbon quantification, including rhizodeposition, as a tool to store carbon in top soil and sub soil on the long term. He is particularly looking at root derived carbon from different plant type or environmental drivers.

Johanne Lebrun Thauront – PhD candidate

Johanne’s project focusses on pyrogenic carbon dynamics at the landscape scale. She particularly works on the watershed of Naizin, Brittany. She is also developing new methods to quantify and qualify pyrogenic matter in soils.
