Skills

Chemical analysis methods (carbon, nitrogen, Van Soest fractionation, polyphenols, ergosterol, fumigation-extraction, enzymatic activities) applied to the biological processes of plant biomass biodegradation in soil.

Measurement of gas flows (CO2, N2O) at the soil-atmosphere interface.

Design of instrumented devices.

Use of stable isotopes, development of 13C and 15N determination methods  (see Laboratoire d’Analyses d’Isotopes Stables, LADIS)

Research interests

They focus on the study of greenhouse gas emissions (N2O, CO2), mineral nitrogen and microbial dynamics during decomposition of crop residues and root litters in soil. More recently, they aim is also to better understand the fiber plant dew retting process in the field. The experimental approaches developed are conducted both under controlled laboratory conditions and in instrumented field devices.

Teaching

Since 2015: 5H TD in Master 2 Plant Biomass Production and Bioprotection (BVPB) of the URCA on the biodegradability of crop residues in soil and the determination of the soil microbial biomass content by fumigation - extraction.
