Patrick Hemberger is currently principal investigator and beamline scientist at the VUV (x04db) beamline at the Swiss Light Source. He graduated in chemistry from University of Würzburg (Germany) in 09/2008 and received his PhD in physical chemistry in 06/2011. Patrick was awarded a Mercator Fellowship from the German Science Foundation (DFG) and has co-authored more than 100 publications in peer-reviewed journals. He is lecturer and local organizer of the Hercules School (2020-2022) in the field of Synchrotron Radiation and supervises PhD students and postdocs. Besides peer-reviewing activities for different journals and funding agencies he is a member of the Proposal Review Panel at Elettra Synchrotron, Trieste (Italy).

At PSI he is responsible for further developing and application of the technologies at the vacuum ultraviolet beamline for chemical reaction dynamics research. This includes development of sources for the generation of elusive and reactive intermediates (free radicals). With the ultimate goal to elucidate reaction mechanism in reactive flows, Patrick  refines the instrumentation at the VUV beamline (spectrometers & sampling environment) to enable combination with novel reactors. He is heading the user chemistry laboratory at the Swiss Light Source, successfully applies for funding and is supervising PhD students and users.

Patrick’s research interests are elucidating reaction mechanisms in reactive environments in all states, phases and time-scales. To unveil these insights, Patrick applies and develops methods to probe elusive and reactive molecules isomer-selectively utilizing vacuum ultraviolet synchrotron radiation, ultrafast lasers, photoelectron spectroscopy and mass spectrometric techniques. Currently he is principal investigator in two projects with the goal to elucidate reaction mechanisms at interfaces including heterogenic catalytic processes as well as in processes involving the liquid phase. Besides projects with VUV synchrotron radiation, Patrick also applies time-resolved photoelectron spectroscopy and mass spectrometry to study the femtochemistry of free radicals.
