Patrick Emmel

I graduated as an Electronics and Physics engineer from CPE Engineering School (Lyon-France) in 1993. The same year I received an MSc in computer science from the University Jean Monnet of Saint Etienne and the Ecole des Mines. In 1993 I moved to the Peripheral Systems Laboratory of the Swiss Federal Institute of Technology (EPFL) in Lausanne (Switzerland). In 1998 I obtained my Ph.D. in computer science.

Since 2002 I'm with Clariant's Masterbatches Division. My research interests include colour prediction, mathematical modelling, spectroscopic measurement, colour printing and history of mathematics.
