Rosan Harmens (PRé Sustainability)
Rosan has an MSc degree in Industrial Design Engineering from the University of Twente. During her masters, she specialized in Management of Production Development and got into touch with life cycle assessment. Within this subject, she found a match between her background in product development, her drive to contribute to a better world, and her analytical and creative skills.
