In the ‘Ultrafast Nanoscience’ group at Umea University we study both the fundamental and applied aspects of light-matter interactions in advanced and multifunctional nano- and meta-materials for opto-electronics, light-based information processing, photochemistry and biotechnology, by using frequency- and time-resolved (magneto-)optical spectroscopy, finite-element computational methods and bottom-up/top-down nanofabrication techniques.
