Research Interests

PhD thesis title: “Testing the drivers and limits of plant species radiations using population genomics”.

My PhD thesis is embedded within a larger research program (SNF Sinergia Consortium POPCORN) on the drivers and limits of species radiations in Neotropical mountains across a range of different spatial, temporal, and taxonomic scales. This Swiss-funded project involves the research groups of Michael Kessler (UZurich), Christian Lexer (UVienna and UFribourg), and Nicolas Salamin (ULausanne) and numerous collaborators in Meso- and South America, the USA, and Europe.

Within this larger research program, I study evolutionary processes in plant species complexes using the tools of population genomics and comparative genomics. Towards this  goal, we sampled species-rich genera of bromeliads (Bromeliaceae; pineapple family) and palms (Arecaceae), with a focus on Tillandsia in bromeliads and Geonoma in palms. For Tillandsia, I also had the opportunity to sample the excellent living collections available at the University of Vienna Botanical Garden and elsewhere in Europe. I use these taxa and samples to study the genomic substrate of adaptive radiation in tillandsioid bromeliads and the genetic mechanisms of population divergence in Geonoma palms. This research involves a variety of NGS-based techniques, including RNA sequencing, whole genome sequencing, and target capture sequencing. I implement this research in close collaboration with Margot Paris, a postdoctoral researcher in our group.
