Maartje Kemmere (1971) received her MSc in chemical engineering at Eindhoven University of Technology in 1995, followed by a Ph D in emulsion polymerisation process development in 1999. Subsequently, she joined the Process Development Group of Eindhoven University of Technology as an assistant professor. Current research areas are polymer reaction engineering with emphasis on supercritical fluids and ultrasound technology, and polymer materials for biomedical purposes. In 2003 she was a visiting scientist at the Flemish Institute for Technological Research. Thierry Meyer, born 1961 in Geneva, obtained his MSc in 1985 at the Swiss Federal Institute of Technology in Lausanne (EPFL), followed in 1989 by a Ph D in chemical engineering. He joined Ciba-Geigy in 1994 as development chemist in the pigment division, then as head of development a.i. to become production manager in 1998. In 1999 he switched to the Institute of Chemical Sciences and Engineering at EPFL to head the polymer reaction engineering unit. Since 2002, he also functions as the chairman of the working party on polymer reaction engineering of the European Federation of Chemical Engineering.
