Summary

Since my bachelor studies in Bonn, Germany, I am interested in the analysis of biogeographical patterns in the Neotropics. After focusing first on the distribution patterns and climatic niche preferences of tree ferns (specifically of the genera Lophosoria and Sphaeropteris) in the Neotropics during my Bachelor’s degree, I compiled a broader biogeographical analysis of vegetation types in South America for my M.Sc. research, also at the Nees-Institute for Biodiversity of Plants in Bonn. Since June 2014, I am a PhD candidate at the University of Zurich in the working group of Dr. Michael Kessler, working on the macroecological side of a joint project (phylogenetics, population genomics and ecology) which tries to identify the limits of species radiations in the Neotropics.

Research Interest

I am interested in the distribution patterns, ecological niche preferences and overall biodiversity of tropical plants, especially of ferns. During the PhD, I will look at how abiotic factors impact the biodiversity of mountain regions, or in other words, why there are different species numbers in regions with similar ecological conditions. The final goal will be a deeper understanding of species diversification processes leading as well to insights on climate change and human impact on ecosystems.
