1998 - Habilited Doctor of Chemistry, (Dr.habil.chem); Specialty: Wood Chemistry
Scientific interests and competence
Wood and lignin chemistry. Synthesis, structure and physico-chemical properties of lignin-containing polyelectolyte complexes. Modification of lignin. Lignin binders and surfactants, their behavior at the different interfaces. Modified lignin products for environmentally friendly “green” technologies (soil structure improvement, prevention of soil erosion, road dust suppressants, emulsion stabilizers, surface modifiers). Hybrid composite coagulants for wastewater treatment (compositions, reactions, application techniques). Lignocelulose functionalization as a filler for biocomposites. Wood-polymer composites (composition, properties, technology, improvement of interface adhesion).
