Our research group has a broad portfolio of activities within equilibrium and non-equilibrium thermodynamics. We combine experiments, theory and molecular simulations to address a variety of scientific and industrially relevant challenges, where sustainability and development of fundamental knowledge is important. Our lines of research are:
