Gunnar Westman

Biträdande professor at Chemistry and Chemical Engineering, Chemistry and Biotechnology, Organic Chemistry

Gunnar Westman is professor in organic chemistry. The overall goal of his research is to modify and find new uses for wood-based products. The research is largely focused on cellulose modification. The goal is to develop new and green materials such as cardboard, textile fibers and nano fibers. Another part of the research is focused on the synthesis of lignin-carbohydrate models that can be used for the development of new chemical modifications of wood.
