I am a botanist and my research interests concentrate on questions of evolution and more specifically, on how interactions could shape biodiversity. I use a broad range of approaches including systematics, taxonomy, macro- and micromorphology, phylogenetic reconstruction, and biogeography.
A key focus of my current and future research is related to plant-pollinator interactions, which are key components of the dynamics of most terrestrial ecosystems. Since species interactions are considered to play a central role in many speciation events, studying the evolutionary history of traits closely linked to this kind of interaction contributes to improve our knowledge of the mechanisms involved. Insects are the largest group of animals visiting flowers to collect mostly pollen and/or nectar, but some insects seek other resources. Relationships between oil-secreting flowers and specialized oil-collecting bees constitute an example of a close and uncommon interaction. Flowers offering oil as a resource are found in only 11 families distributed across the angiosperms among unrelated orders, including Iridaceae where oil rewards evolved multiple times.
The goal of my research is to improve our knowledge about the evolutionary history of this uncommon pollination system and to test whether the evolution of this uncommon pollination system is a causal factor of diversification among Iridaceae from the Neotropics.
