Jean-Pierre Verbelen studied Botany (M.Sc., 1969) at the University of Gent and obtained his PhD in 1976 at the University of Antwerpen, where he actually is Professor at the Department of Biology. Major research interests are plant development, cell expansion and cytoskeleton involvement. Kris Vissenberg studied Biology (M.Sc., 1997) and obtained his PhD at the University of Antwerpen in 2001. Actually he is a post-doc at the Fund for Scientific Research - Flanders (FWO-Vlaanderen). Major research interest are cell expansion, cell wall metabolism and general plant development.
