Gunnar von Heijne is Professor of Theoretical Chemistry at Stockholm University since 1994. He studied Chemical Engineering at the Royal Institute of Technology, Stockholm, and received a PhD in Theoretical Physics from the same institution in 1980. Among other awards and honors, he has received the Accomplishment by a Senior Scientist Award of the International Society for Computational Biology (2012) and the Novo Nordisk Foundation Novozymes Prize (2018). He has worked mainly on problems related to protein sorting and membrane protein biogenesis and structure. The work includes both bioinformatics methods development (e.g. methods for prediction of signal peptides and other sorting signals as well as prediction of membrane protein topology) and experimental studies in E. coli and eukaryotic systems.
