Research Interests

I’m an ecologist with a background in physics, with an interest in animal movement and foraging ecology. My research bridges the disciplines of physics, meteorology, computer science and ecology, addressing questions on the effects of global change on the distribution and seasonal migration of birds.

At Cornell Lab of ornithology I’m currently studying the migration corridors of small songbirds at the scale of a full continent, a perspective that is still largely missing, but that has come into reach through the use of meteorological weather radar networks in animal migration studies.

At the Netherlands Institute of Ecology I recently studied the migration and habitat requirements of Brent Geese, a small goose species that breeds in the high arctic, which in winter is highly dependent on natural eelgrass habitats, one of the most endangered ecosystems in Western Europe.

In the European Network for Radar surveillance of Animal Movement (ENRAM) I lead the algorithm development working group, in close collaboration with the computational geo-ecology group at the University of Amsterdam.

Recent Projects

Energetics of long-distance migration

How do Dark-bellied Brent Geese (Branta bernicla bernicla) prepare in the Dutch Wadden Sea for their fast migration to Taimyr peninsula in Russia?

Flight behaviour of Common Swifts

Common Swifts (Apus apus) are specialist flyers which spend nearly their entire life on the wing. At night they show impressive (and puzzling) flight behaviour.
