Wood is a source of fibers, nanoparticles, semicrystalline and amorphous polymers. My research is on engineering these components into hierarchical materials with a function. The core is to build from liquid-rich state, gels, emulsions, dispersions, solutions, colloids toward solid organizations. I combine forest products technology, materials science and renewable resources for advancing sustainable materials engineering. The research efforts involve cellulose, hemicelluloses and lignins with emphasis on surface, interface, and intermolecular interactions. I am part of WWSC (Wallenberg Wood Science Center) and aWCplatform (All-Wood Composite platform). The theme of the former is “New materials from trees”. In the latter I develop continuous crystalline cellulose film composites with controlled organization. I do not work on current applications but look into discovering new. What do you think these materials are good for?

I have been at Chalmers since 2017.
Current research projects: 
Oxidized hemicelluloses for films and gels (Vetenskapsrådet)
Wood-polymer films -surface matters (WWSC)
HEMISURF (SNS)
Cellulose nanomaterials in flow (AoA Materials, Chalmers)
Hydro and oleogels for medical technology (Kristina Stenborg Stiftelse)

Master and Bchelor students! We have  thesis topics available in the following areas: 
Assembly of cellulose nanomaterials to films
Photopatterning of celluloses for capillary separation (with Rise and TUGraz)
Simultaneous extraction and oxidation of hemicelluloses (with BillerudKorsnäs)
Development of physico-chemical analysis of cellulose by refractive index (Bachelor thesis work)
