Personal profile
Research expertise
His research within the estuaries team focuses on the development, evaluation and management of nature compensations and restoration projects in the Antwerp port area, with a focus on the hydrological situation and vegetation development. The aim of this research is to support the policy authorities with advice in order to achieve a good conservation status.
In addition, as a bat expert he conducts research into landscape use and habitat use of bats. An important part of this research is hibernation of bats. In this research, the temperature evolution in hibernacula is investigated and physical models are built to understand the habitat preference of hibernating bats, to optimize bat hibernacula and to investigate the influence of climate change on hibernating bats. He also investigates bat activity and landscape connectivity, with a special focus on winter activity.
