Research Interests

Prof. Hagn's research is focused on nuclear magnetic resonance (NMR) spectroscopy of membrane proteins. This protein class is essential for signal transduction and the transfer of proteins and small molecules across the biological membrane barrier. The key to understanding these processes is to study these systems in a native environment provided by a phospholipid bilayer. Biologically relevant systems of interest are mitochondrial membrane proteins, G-protein coupled receptors (GPCRs) and their associated G-proteins, which are involved in metabolic diseases, neurological disorders and cancer.
