Skills

Processes: biological transformations of organic matters (soils, mulch, composting, retting). Interactions between lignocellulosic substrates and microorganisms. Interactions between organic pollutants and organic matter. C storage, organic matter mineralization.

Modeling: EEZY, GDM, CANTIS, COP-Compost, “residue” module of STICS, RothC, “RETTING” module, etc.

Experiment: enzyme assays, experimental devices, microcosms, respirometry, biochemical analyses (residues, organic wastes), organic pollutant speciation, isotopic labeling (14C), fungal growth.

Statistics: indicator and typology calibration of degradation behavior

Research interests

My research activities concern the modeling of the biodegradation processes of plant biomasses (crop residues, roots, forest litter) in soils or at their surface. Their aim is to improve our understanding of the interactions between microorganisms and their decomposing substrates and the representation of these interactions in numerical models. I am particularly interested in the microbial physiological and enzymatic responses in function of the chemical and physical traits of organic substrates. Timescales vary between days and years and spatial scale are fine (µm3 to cm3).  The issues are to better understand decomposition process in order to be able to better integrate nutrients recycling in agroecosystems management and better predict organic matter stabilization and C storage in soils.

See also Sylvie Recous, Hugues Clivot, Guillaume Humbert scientists in the same lab for further information about our activities.
