Peter Eshuis was born in Hengelo, the Netherlands, on the 12th of January 1980. He attended high school at “De Grundel” (Hengelo), from which he graduated in 1998. Subsequently, he started studying Applied Physics at the University of Twente in Enschede. In 2002 he performed his three months internship in the research group of Prof. dr. Heinrich Jaeger and Prof. dr. Sid Nagel at the University of Chicago (USA) on “The Multi Intruder Brazil Nut Problem”. Here he really got into research on granular matter. Back at the University of Twente he continued granular research with a graduation project in the Physics of Fluids group of Prof. dr. Detlef Lohse. On the 29th of August 2003 he obtained his Master’s degree cum laude on the topic “Leidenfrost Effect and Coarsening in a Granular Gas”.He carried on with scientific research as a PhD student under supervision of Prof. dr. Detlef Lohse, Prof. dr. Ko van der Weele and Dr. Devaraj van der Meer at the Physics of Fluids group in Twente, with occasional work visits to the University of Patras (Greece). The results of the research performed in this period are described in his thesis: "Collective Phenomena in vertically shaken Granular Matter".Specialties: Physics, dynamics of granular matter, image analysis, experiment, theory, numerics
