Research Interests

As I have always been fascinated by the diversity of plants, I chose to study plant sciences for my Bachelor and Master studies at Wageningen University. During my Master, I became more interested in understanding plant evolution and its drivers. This led me to choose subjects for my research internship and MSc thesis that allowed me to dive deep into the evolution and trait diversity of several diverse plant groups. Inspired and motivated by these projects, I started my PhD research for which I am investigating the evolutionary history of the highly allopolyploid fern genus Cystopteris in Europe using genomic and phenotypical data. This work aims to uncover the complex relationships within this genus, to understand how characters evolve in such a system, and to get an insight into the true taxa of Cystopteris in Europe.
