MB is the research group leader of ‘Isodrones’ at the TU Braunschweig, Germany. In Isodrones - funded for 5 years by the Volkswagen Foundation - he and his team is creating innovative, application-oriented methods to study the system soil-plant-atmosphere. By combining classical methods with novel, in situ soil and plant water isotope measurements and UAV-based approaches, the ultimate goal of Isodrones is to measure water uptake from deep soil/groundwater completely non-destructive.
