Biography

Torbjörn Pettersson is an Associate Professor at KTH Royal Institute of Technology, specializing in wood components, chiefly cellulose fibers and fibrils. His research focuses on the defibrillation process, modifications of fibrils, and compatibility issues related to incorporating fibers and/or fibrils into composite materials. Pettersson is involved in improving the functionality of JKR-instruments, facilitating semi-automated and automated image analysis for measuring interactions among wood biopolymers. His expertise includes advanced Atomic Force Microscopy (AFM) techniques for high-resolution measurement of force and surface topography. He has a strong background in surface interactions and modifications, having worked with polyelectrolytes, proteins, and living cells in various research contexts. His early career at Akzo Nobel sparked his interest in surface chemistry and adhesion, further developed during his PhD studies at KTH. His publications and academic contributions emphasize the structural and chemical properties of wood-based materials and their interactions.
