Violaine Berger, Director Ecosystems & Landscape Management Cluster, WBCSD.

He was confortable working with short deadlines and he will remain an asset to the project." Juan Simon, Project Manager, ISO Academy, International Standardization Organization.

Samuel is an original thinker - inquisitive, proactive, and challenging. He has been very good at building a network and is always willing to engage and bring people together to further the agenda on valuation methodologies this is vital at this stage in the development of natural capital valuation techniques.

"I have primarily worked with Samuel at the intersection of biodiversity and LCA. Where many LCA practitioners might reject scientific practices from other fields if they don’t easily fit in to LCA, Samuel seeks to fully understand the complexities and work towards a solution – bringing the best of both worlds. He is a rare combination of thoughtfulness and technical rigor – matched with strong project management skills. I have truly enjoyed working with him and appreciate his contributions to the field.” - Martha Stevenson, Director Forests Strategy and Research, WWF US.
