Peter Hommelhoff is Max Planck Research Group Head at MPQ in Garching, Germany, since 2008. After his physics studies at Technical University of Berlin and the Swiss Federal Institute of Technology (ETH) in Zurich, which conferred the diploma to him, he obtained his PhD from Ludwig Maximilian University of Munich working in T. W. Hänsch's atom chip group. Together with M. Kasevich at Stanford, as a Lynen-Fellow of the Humboldt Foundation and later Trimble Fellow, he started the field of ultrafast electron emission from nanometric tips, which led to attosecond science with metal nanostructures.
