AMBLES André

Professor

Research Topics

(Bio) organic geochemistry.

– Organic matter of soils and sediments (lipids, humic substances, kerogen): molecular structure, biogeochemical processes of evolution, accumulation (sedimento).
– Valuation of lignocellulosic biomass.
– New strategies for the study of complex organic materials (chemical, pyrolysis, thermochimiolyse).

Keywords
