My objective is to respond to an environmental issue using different spectral techniques (UV-visible, near IR, medium IR, NMR, etc.). ¹³C) and reference techniques (chemical analyses, chromatographic techniques). To correlate these multi-source data, I use statistical tools (design of experiments, Principal Component Analysis, curve resolution methods and predictive methods) to identify chemical markers for understanding the evolution of the systems studied. I interpret the spectral changes (1) of various plant species due to thermal, photochemical, hydric or saline stress, etc., in order to understand the role these stresses play in the deterioration of plant material and therefore in the turnover of organic matter, (2) to different soils by considering the bioclimatic contexts to which they are constrained, their uses and agricultural practices in order to develop a predictive tool for current ecology.
