I study movement and change. My research covers different phenomena, actors,
and scales, both in space and time, from local to global, from snapshots of human
activity to century-long historical processes. During my PhD studies, I focused on the local scale, exploring urban traffic with GPS movement data. As a URPP Language and Space group leader, my focus has shifted to the regional and global scale. In the Spatial Data Science group, we study the role of geography in the diffusion of linguistic families, explore the co-evolution of culture and genetic variation, and develop Bayesian models to detect past human interaction and contact.
