Research profile

My current research focuses on the assimilation of remotely sensed crop biophysical parameters into the crop modeling framework SIMPLACE, aiming at improving the framework’s performance at sub-field, field and regional level. For this purpose, I rely on a broad set of remotely sensed data, including multispectral satellite data, UAV imagery and field-based measurements.

Current study sites are located in Germany, France and Netherlands. Past research took me to pastures and cropping sites in South Africa.

My PhD thesis ( investigated the potential of UAV based low-cost camera imagery for measuring biophysical variables in maize.
