Maths Karlsson

Full Professor at Energy and Material

Maths Karlsson is since 2023 Professor in Materials Science. Prior to his appointment at Chalmers (2011), he was employed as a scientist at the European Spallation Source in Lund (2008-2011), where he, outstationed to the Institut Laue-Langevin in Grenoble, France, was engaged in the development of new neutron scattering methods. He has also been a visiting scientist at Iowa State University (2004) and University of California in Santa Barbara (2012-2013). His research group focuses on studies of various fundamental aspects of structure and dynamics in functional - mostly energy relevant - materials, such as proton conducting oxides, mixed-anion compounds, metal halide perovskites, and inorganic phosphors, with a view towards their application in various technological devices (e.g., solid oxide fuel cells, solar cells, and light-emitting diodes) or for use in catalysis. A unifying theme in almost every aspect of this research is the goal to develop a detailed understanding of the coupling of the materials' functional properties to their atomic-scale structure and dynamics. The research is mainly experimental in nature. The primary tools to this end involve the use – and development – of advanced neutron and x-ray scattering techniques, vibrational spectroscopy, and optical techniques for studies of luminescence.

 

Maths is chairman of the Faculty Assembly of the Department of Chemistry and Chemical Engineering and a member of Chalmers Faculty Senate.
