My research aims to contribute to a better understanding of the spatiotemporal dynamics of biodiversity at various hierarchical levels (genotypes, populations, species and communities). To this end, I study how biodiversity dynamics arise from fundamental demographic processes (birth, death and dispersal of organisms), and how these demographic processes are in turn coupled with evolutionary processes and biotic interactions. Much of my work is motivated by the need to quantify and forecast ecological and evolutionary dynamics under environmental change. To address my research objectives, I use statistical methods that quantitatively integrate theory- and process-based models with various types of data.
