The concept of multiscale modelling has become progressively more accepted as an engineering tool in modern science and technology. The most important variant of contemporary multiscale modelling is given by the combination of quantum mechanics and classical physics, which, in a sense, gives the possibility to join the accuracy and rigor of the former with the applicability of the latter. It gives a possibility to find working approaches that can accurately address the nanoscale, which is of obvious importance for materials science (nanotechnology) and life science (early stages of diseases and drug design), and where each of the two (quantum and classical) models by themselves has shortcomings. These quantum-classical approaches have secured applications in a wide variety of applied research areas, such as chemistry, biotechnology, biomedicine and materials research. In this lecture, the speaker will shortly review some typical work in his lab of multiscale modelling of light-matter interaction for addressing general properties and spectroscopy of molecular systems in homogeneous and heterogeneous environments. Applications cover various types of spectroscopy and linear and nonlinear properties of molecules in solution, on surfaces, in confined biological environments or in combinations of such environments.


About the speaker

Prof. Hans Ågren received his PhD in Experimental Atomic and Molecular Physics from Uppsala University in 1979. He joined the Lund University in 1981 as an Assistant Professor and returned to Uppsala University in 1983. In 1991, he was appointed the Chair Professor in Computational Physics by Linköping University and he moved to the KTH Royal Institute of Technology in 1998, where he is currently the Senior Professor of Theoretical Chemistry and Biology. He has also been the Senior Professor in Theoretical X-ray Physics of the Uppsala University since 2018.

Prof. Ågren’s research interests focus on the areas of molecular/nano/bio photonics and electronics, computational nano- and bio-technology, being a mix of method development and problem oriented applications in collaboration with experimentalists.

Prof. Ågren received the Changjiang Distinguished Professorship (2017) from the Chinese Ministry of Education and the Björn Roos Award (2014) from the Swedish Chemical Society.
