Gerrit Polder is senior researcher Image Analysis and Machine Vision at the department  Greenhouse Technology of Wageningen University and Research Center. In 1985 he obtained a B.Sc. in electronics at the HAN University of Applied Sciences in Arnhem the Netherlands. After working several years in image processing and related topics, in 2004 he got a Ph.D. from Delft University of Technology on spectral imaging for measuring biochemicals in plant material. From 2004 he works at Wageningen University on machinevision and robotics projects in agriculture.
With protected cultivation and arable farming as main application fields, his research interests include imaging spectroscopy and spectral imaging for disease detection and high throughput automated plant phenotyping. Furthermore he worked on sensor fusion (color, fluorescence and infrared) for monitoring plant health using a robot system, and other projects mainly focused on agricultural research. He is (co-)author of 3 book chapters and more than 80 papers in peer reviewed journals and conference proceedings
