Title: Surface investigations of catalytically active intermetallic PdGa

Roland Widmer is a senior scientist at the Swiss Federal Laboratories for Materials Science and Technology (Empa) in Dübendorf, Switzerland. After he performed his Diploma and PhD thesis in electrolytic in-situ scanning probe microscopy at the Department of Chemistry and Biochemistry at the University of Bern under the supervision of Prof. H. Siegenthaler, he joined Empa in 2003 and visited the group of Prof. K. Horn at the FHI in Berlin for a sabbatical in 2008. The main focus of his research is to understand the structure and reactivity of (complex) surfaces and processes at surfaces at a molecular and atomic level mainly applying scanning probe and X-ray photoelectron emission techniques.
