Current Research Topics
My current research focuses on the ecology along rivers in agricultural landscapes. I am interested in understanding how human activities interact with biodiversity in rural watersheds. Consequently I work in restoration ecology of the riverscapes, including headwater systems. I also develop research in partnership on spatial analysis of ecological data at different scales and in different shapes of landscapes. Concerning landscape ecology in the context of river survey, I focus, for example, on questions on how and why to restore connectivity and the river continuum. Temporal scales are also considered, using eco-historical approaches when possible. I promote networking for ecological restoration with stakeholders involved in river management, considering their views or empirical knowledge. I also try to relate this information to ecological concepts and vice versa.
