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.

This research aimed to combine the two LCA approaches, and a conceptual social impact assessment method which she applied to different case studies. Rosan contributes to the team as trainer and gives support to partners.
