I teach different courses in Masters and Bachelor levels mainly focusing on wood properties, wood anatomy, liquid impregnation, preservation and research methodology.
My field of research interest is in liquid movement in wood, wood anatomy, wood modification, preservation and wood drying. I am also interested in non-destructive evaluation of wood and wood-based composites. I give emphasis on wood modification in an environmental benign way.
