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 in agriculture-forest frontiers, and aims at guiding biodiversity conservation strategies in the face of global changes. [See reseach focus here.] 

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. 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).

During her PhD at the Potsdam Institute for Climate Impact Research (PIK) in Germany and the National Institute for Space Research (INPE) 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.
