Personal profile
Short presentation
I am an assistant professor in Experimental Electrochemistry in the Center of High Entropy Alloy Catalysis (CHEAC) at the Department of Chemistry, where I research nanomaterials in electrochemical energy conversion reactions.
Primary fields of research
My research group works on developing and testing new electrocatalyst for energy applications, with a strong focus on the structural structural characterization of catalysts using X-ray based techniques (absorption, scattering). To understand the structure of catalysts during the reaction we use advanced X-ray characterization at large scale research facilities.
Teaching
I am course responsible for the elective course BSc course Chemistry in the Green Energy Transition. I am also a lecturer in the MSc course Structural Tools in Nanoscience and teach in the introductory first year BSc chemictry course Inorganic Chemistry 1 - Uorganisk Kemi 1 (KemiU1)
