About us Practical matters How to find us prof. dr. T. (Theunis) Piersma

Research interests

Theunis Piersma is the founder and scientific director of the RUG newly created interdisciplinary BirdEyes - Centre for Global Ecological Change at the Faculties of Science & Engineering and Campus Fryslân. BirdEyes is an experimental science and creative centre that views the world through the eyes of birds. More and more birds are flying around with tiny transmitters, loggers and other high technology on their backs and legs. This generates an unimaginable amount of information. By cleverly combining such data with other sources of information, and by using new ways to tell stories and share the insights with, BirdEyes strives to open up a new knowledge network. The centre aims to be an innovative part of the University of Groningen, with empirical and inspirational roots in the farthest corners of the world.
