Background and activities
Vice Dean for Education at the Faculty of natural sciences.
Course responsible for KJ2031 Advanced Inorganic Chemistry and KJ2900 Bachelor project in Chemistry.
Research interests include synthesis, functionalisation and characterisation of porous materials.
Project leader of a cross-disciplinary project on the functionalisation of silica aerogels for catalytic applications.We are focusing on the introduction of cationic metal precursors and studying their interactions with the gel, also including formation and stabilisation of metallic and bimetallic nanoparticles.
This research was described in the norwegian website "forskning.no" in December 2013:

Other research projects include synthesis and fundamental characterisation of porous materials such as zeotypes with emphasis on incorporation of catalytically active transition metals. Ongoing projects also include modification of porosity in zeotypes with the aims of introducing mesopores which can function as super-highways to microreactors. We are experienced users of synchrotron facilities such as the Swiss Norwegian Beamlines (SNBL, pictured below) in Grenoble France, and the EXAFS beamline at MaxLab in Lund Sweden. In situ x-ray absorption spectroscopy studies of our materials under realistic working conditions help us understand and identify metal species present during the reaction.
