Research Interests

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.

Projects (funded by the German Research Foundation):

I am currently postdoctoral researcher in the Biodiversity Enrichment Experiment in Oil Palm Plantations of the Colaborative Research Center "Ecological and Socioeconomic Functions of Tropical Lowland Rainforest Transformation Systems (Sumatra, Indonesia) - EFForTS"

I previously investivated vegetation-rainfall feedbacks in the Amazon region as part of my PhD in the International Research Training Group "Dynamical Phenomena in Complex Networks".
