Dr. (Delphine) Clara Zemp
I focus my research on understanding mechanisms and dynamics linking vegetation, climate and land use in tree-based natural and agricultural systems, with the aim to support sustainable landscape and ecosystem management strategies. I am interested in combining various methodological approaches including remote sensing, model development and ground-based measurements. I have experience in using techniques from complexity sciences (such as complex networks and complexity measures in time series) to analyze non-linearities, feedbacks and interactions in the system at various spatio-temporal scales.
