Sebastian completed his PhD at the University of Cambridge in 2006 on energy transfer processes in organic semiconductors. After an additional year as a junior research fellow in Prof. Friend's group in Cambridge, he arrived in Sweden in 2007 to investigate conformational dynamics of membrane proteins.
Since 2011 he has turned independent with funding through an Assistant Professorship position, sponsored by the Swedish Research Council, a 'Future Research Leader' research award from the Swedish Foundation of Strategic Research and an ERC starting grant. The goal of his research activities are to explore molecular structural dynamics (see projects).
