Alexandra Hees received her doctorate from the University of Cologne in April 2020. In her dissertation, “Eine ‘grüne’ Zukunft für Kunststoffe? Die Entwicklung von Märkten für Biokunststoffe,” she explores the tension between perceptions of the future and market creation processes, reconstructing the development of markets for bioplastics from the 1970s to the present day from an economic sociology and cultural sociology perspective.
