...has worked extensively on the mathematical side of the topic during his PhD studies, with experience in both Bose and Fröhlich polarons. He extended his toolkit and overview of similar subjects during the concluding postdoc in a theoretical physics group, where his research was devoted mainly to the cognate topic of charged Fermi polarons. He provides a background in mathematics that is combined with insights from physics, including first-hand acquaintance with recent experimental developments
