Research interests

Organic matter recycling in soils, plant nutrition, Rock-Eval analyses on soil samples, soil physical properties, data collection and analysis

ALAMOD project - Process and disseminate data collected in a previous project, COLLECT-OR. A dataset composed of carbon and mineral nitrogen mineralization dynamics in the soil and chemical analyses (carbon and nitrogen contents, Van Soest biochemical fractions: soluble, hemicellulose, cellulose, lignin) from approximately 420 plant litter samples. The data will be upload in a data repository (Recherche.Data.Gouv). The work will be valued through a data paper and a regular paper.

Teaching

Teaching at the University of Reims Champagne-Ardenne (32 hours)
