Her researches are focused on the use of remote sensing technologies combined with statistical or biophysical modelling to (1) improve the cropping systems descriptions and (2) improve the assessment of agronomical and environmental performances of smallholder cropping systems. Over the last years she worked mainly in West Africa, with a focus on agroforestry systems. She was previously seconded to Centre de Suivi Ecologique in Senegal and she is now based at IITA Nairobi in Kenya where she conducts her research on yield gap assessment in Ethiopia .
