Professor Tatjana Stevanovic has completed her undergraduate and graduate studies up to Ph.D. at the University of Belgrade, Belgrade Serbia, at which she has been teaching Wood Chemistry and Chemical Technology of Wood since 1997. Tatjana is a Professor at Laval University, Quebec, Canada, where she teaches courses on chemistry and chemical engineering of wood. She has been performing research on bioactive polyphenols from forest biomass along with studies on wood polymers, notably on lignins and their applications in materials. Professor Stevanovic has published numerous scientific papers and book chapters while acting as a scientific editor of two recently published books on the properties and transformation of biopolymers and extractable molecules from lignocellulosic. She has published an international patent on a new catalytic organosol process leading to highly pure lignin. She is the director of the wood engineering program at the Department of wood and forest sciences of the Laval University, where she teaches and conducts research. She is a fellow of the International Academy of Wood Science.
