As an evolutionary biogeographer, I am interested in the origins of species distribution patterns over timescales of millions of years. Specifically, I try to understand the roles played by selection and adaptation versus evolutionary contingencies such as dispersal and drift. DNA sequencing and phylogenetic modelling are the main methods I use. My current projects focus on grasses (Poaceae, one of the world’s most widespread plant families), the biomes of Madagascar, and plant-associated fungi.
