Research Interests
I am interested in diversity patterns and the biotic and abiotic factors and mechanisms driving them. Especially, the processes creating the apparent spatial patterns of plant diversity such as speciation and dispersal interest me. My current research focuses on taxonomic, functional and phylogenetic diversity and turnover of plants at macroecological scale, especially on islands and island-like systems.

I am a biologist by training with a background in Tropical plant ecology. During my PhD under supervision of Holger Kreft, I studied "the Macroecology of island floras". Currently, I am working as a postdoc in the BEFmate project, subproject A2: Biodiversity and metaecosystem dynamics - spatial patterns of community structure and functioning. The project addresses how spatial processes such as dispersal and random colonization events simultaneously affect biodiversity, the species composition of communities and their functional consequences across marine and terrestrial island-like ecosystems.
