Topics
With the analyses of C, N, H, and S stable isotopes (δ13C, δ18O, δ15N, δ2H, δ34S) in environmental samples, from soils to sediment and water we study:
–         Effects of changing environmental conditions on the mechanisms and rates of C      stabilization in soils
–         Interactions between land degradation and C sequestration in soils
–         Reconstruction of past environments and climates to improve future predictions
–         Fate of organic pollutants in soils, sediments and water and interactions with organisms exposed to pollution
–         Application of CSIA in forensic science
