Ulrich Keyser is Professor of Applied Physics at the Cavendish Laboratory, University of Cambridge, where he leads pioneering research on nanoscale transport phenomena. Trained in experimental physics at Leibniz University of Hannover, he earned his PhD in 2002 on nanolithography using atomic force microscopy. Following postdoctoral work with Cees Dekker at Delft University of Technology and Friedrich Kremer at Leipzig, Keyser established his independent group through the German DFG Emmy Noether Program before joining Cambridge in 2007. His research focuses on nanopores, single-molecule biophysics, and out-of-equilibrium polymer dynamics, with applications in biosensing and nanotechnology. He has been awarded prestigious grants, including ERC Starting and Consolidator Grants, and honours such as the Helmholtz Prize for Applied Metrology and the Institute of Physics Sam Edwards Medal. Beyond research, he contributes to teaching and mentoring at Gonville & Caius College, Cambridge, inspiring the next generation of physicists.
