Thomas Princen is Associate Professor of Natural Resource and Environmental Policy at the University of Michigan. He has a background in biology, political science and economics and his research focuses on issues of social and ecological sustainability with a primary focus on sufficiency. In this podcast Professor Princen shares his views on sustainable organisations and, specifically, whether an organisation can be sufficient, efficient and grow at the same time. We also discuss how the principles of sufficiency can be integrated in management education and research. oikos PhD fellow Liudmila Nazarkina met Thomas Princen at the 2012 Gronen Conference.
