Delphine Clara Zemp

Clara Zemp is Assistant Professor and head of the Conservation Biology Lab at the university of Neuchâtel. Her research lies at the interface between biodiversity, climate and land use at the agriculture-forest frontiers. It focuses on the importance of tree diversity and cover to (1) provide habitat for biodiversity across various groups of organisms (multidiversity), (2) support multiple ecosystem functions and services for society (multifunctionality), and (3) maintain the resilience and ecological integrity of ecosystems facing land-use and climate changes. Hence, her research addresses fundamental research questions in ecology and aims at guiding biodiversity conservation and ecological restoration strategies in the face of global changes.

Prior to joining the university of Neuchâtel, she was working at the university of Göttingen in Germany as postdoctoral researcher and scientific coordinator of the Biodiversity Enrichment Experiment in oil palm plantations (EFForTS-BEE). This interdisciplinary research platform is part of the largest network of biodiversity experiments worldwide (TreeDivNet) and the Collaborative Research Centre on “Ecological and Socioeconomic Functions of Tropical Lowland Rainforest Transformation Systems (Sumatra, Indonesia)” (EFForTS), in which she is still involved today as associated scientist.

During her PhD at the Potsdam Institute for Climate Impact Research (PIK) in Germany in collaboration with the National Institute for Space Research (INPE) and the university of São Paulo (USP) in Brazil, she studied interactions between the Amazon forest and climate. After receiving a doctoral degree from the Humboldt University in Berlin in 2016, she was awarded a start-up grant to conduct research on deforestation effects on Amazon forest resilience.
