A warm welcome to Jérôme Guélat, who is starting his PhD degree in February. Jérôme’s PhD is an exciting collaboration with Dr. Marc Kéry from the Swiss Ornithological Institute, where Jérôme has been working as a GIS specialist. For his PhD, he will investigate the spatiotemporal dynamics of breeding bird populations across Switzerland using a hierarchical model and disparate data collected over large spatial and temporal scales. We are looking forward to having him on board as our spatial analysis expert and embassador of the Vogelwarte.
