Diana Visser is Vice President of Sustainability at Corbion, a sustainable ingredients company dedicated to preserving what matters. Corbion specializes in lactic acid, lactic acid derivatives, food preservation solutions, functional blends, and algae ingredients, leveraging its advanced capabilities in fermentation and preservation technology to help differentiate products in food, home & personal care, animal nutrition, pharmaceuticals, electronics, medical devices, bioplastics, and more.

As VP of Sustainability, Visser leads the development of Corbion's long-term sustainability strategy, ambitions and measurable targets. She attended TU Delft, where she earned her MSc in chemical engineering and her PhD in biotechnology with a focus on metabolic engineering. Visser joined Corbion in 2001 in the role of scientist, contributing to the company's fermentation, metabolic engineering and process technology development, before progressing through a variety of managerial roles. After being appointed as Sustainability Director in 2015, she aligned Corbion's sustainability strategy with the UN Sustainable Development Goals (SDGs), and endeavored to more fully integrate sustainability into Corbion's overall business strategy.

Jean-Paul Meijnen


Jean-Paul Meijnen is Senior Director Organism Engineering at Ginko Bioworks, and Managing Director at Ginko Bioworks Netherlands. The mission of Ginko Bioworks is to make biology easier to engineer, using state of the art technology for DNA synthesis, laboratory automation, and high performance analytics. 

The resume of Jean-Paul Meijnen is impressive. He studied in Wageningen, did a PhD in Delft and a post doc at the Flemmisch Institute for Biotechnology. He then switched gears and moved to industry in the role of Scientist with Dyadic, which was later acquired by DuPont Industrial BioSciences, focussing on enzyme production and innovation. In 2018 he joined Dutch DNA Biotech, where he became director of R&D and responsible for the platform technology to develop fungal strains and fermentation processes for the production of proteins and organic acids. After Dutch DNA Biotech was acquired by Ginko Bioworks, Meijnen continues his work on engineering microbes for a wide range of applications, and is in charge of the Dutch foothold of Ginko Bioworks.
