Bjoern Hagen holds an MSc in Spatial and Environmental Planning from the University of Kaiserslautern, Germany, and received his PhD in Environmental Design and Planning from Arizona State University. Dr. Hagen is currently an Assistant Research Professor and Lecturer in the School of Geographical Sciences and Urban Planning at Arizona State University.
Dr. Hagen has worked on projects focusing on sustainable urban and regional development with the Development Agency of Rhineland Palatinate (Entwicklungsagentur Rheinland-Pfalz e.V) and the redesign of the UNESCO World Heritage site Völklingen Ironworks towards a sustainable future. In recent years, he has conducted research in the areas of climate change mitigation and adaptation, public risk perception, and risk communication. By studying the nature of public perceptions of global climate change in different countries and over time, his research contributes to improving climate change communication efforts to reduce greenhouse gas emissions and to increase the adaptive capacity and resiliency of urban environments.
