Stéphanie is interested in understanding how plants integrate and respond to different environmental conditions such as nutrient availability and the presence of neighbour (e.g. weeds). Her research aims to provide useful information for the development of crop varieties (especially wheat) that can produce high yield with lower herbicide and fertiliser inputs. Through collaboration with Ethiopia and India, she has an interest in millet species (e.g. foxtail millet, pearl millet and finger millet) as well as tef (Eragrostis tef).
