Maths Karlsson

Associate Professor, Chemistry and Chemical engineering/ Energy and Material

Maths Karlsson is Associate Professor at Chalmers. 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 ionic conductors and luminescent materials, with a view towards their application in various technological devices (e.g., solid oxide fuel cells, batteries, solar cells, and light-emitting diodes). 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 primary tools to this end involve the use and development of a broad range of neutron scattering techniques, and vibrational spectroscopy, often complemented with computer modelling by collaborating research groups.

Maths is member of Chalmers Faculty Senate and he is vice chairman of the Faculty Assembly of the Department of Chemistry and Chemical Engineering. Furthermore, he is chairman of the Swedish Neutron Scattering Society (SNSS) and the Swedish delegate of the European Neutron Scattering Association (ENSA).

Please see our poster describing some of our research.

PhD courses

  • Neutron spectroscopy, FFY005 (3 ECTS). - The course gives an introduction to neutron spectroscopy (inelastic and quasielastic neutron scattering) and is given within the framework of the Swedish Research School on Neutron Scattering (SwedNess,

MSc courses

  • Synthesis, Structure and Properties of Solid State Materials, KOO093 (7.5 ECTS). - The overall aim of the course is to give a good understanding of the synthesis, structure and properties of inorganic materials in the solid state, and to illustrate the technological applications of such materials. In addition an understanding of the relations between structure of materials and their properties will be obtained. 

Bachelor courses

  • Fysikalisk Kemi, LKT053 (9 ECTS). - Kursen skall ge grundläggande och vissa fördjupade kunskaper i fysikalisk kemi som fordras för fortsatta studier i kemi och kemitekniska ämnen. Den ska ge förståelse för hur gaser, vätskor, lösningar och blandningar uppträder under olika fysikaliska förhållanden. Vidare skall kursen ge grunder i kemisk termodynamik, termokemi och elektrokemi. Projektdelen skall ge träning i planering, ansvarstagande, handledning, kommunikation och presentation, som förberedelse för yrkeslivet.
