During my career at Wageningen University and Research I have been responsible for the execution of projects and activities related to agro-meteorology and remote sensing. This includes the set up of crop monitoring systems in the EU within the framework of MARS as well as dedicated systems in Russia, China and Morocco. Further, I cooperated in international teams on various research activities related to integrating crop models and remote sensing which led to a PhD and several well cited publications. More recently, I worked within our team to apply the same technologies for supporting smallholder farmers in developing countries (Bangladesh, Ethiopia, Myanmar) with crop advisories integrating agronomic and weather information. Finally, I am a lead developer of some important software packages such as WOFOST, the PCSE modelling framework and derived packages like the CalibrationManager which has been used to calibrate the WOFOST model with the MARS system.
