Plant Evolution and Systematics

The fundamental goal of my research is to understand the evolution of plant diversity. To achieve this goal, I integrate different aspects of plant evolutionary biology into a phylogenetic framework. My research includes a range of experimental approaches, from the collection and observation of species in the field to the generation of molecular cytogenetic and DNA-based data. My main research projects include:

1. Evolution of breeding systems, biogeography, and polyploidy in the arctic/alpine genus Primula. This project focuses on elucidating the transitions between homostyly-heterostyly and diploidy-polyploidy in response to Pleistocene climate changes;
2. Testing the out-of-India origin of selected plant families by using molecular dating approaches. This is mainly a biogeographic project aimed at assessing the congruence between phylogenetic and geologic patterns centered around the role of the Indian plate in biotic exchanges;
3. Elucidating the origins of Mediterranean biodiversity with molecular phylogenetic and dating methods: the biogeographic history of the Corso-Sardinian flora;
4. Phylogenetic relationships and genetic diversity of Saxifraga florulenta, a rare species endemic to the Maritime Alps.
