Steven-BloembergenSteven Bloembergen, Ph.D.
Founder, Chairman and CEO

Dr. Steven Bloembergen has 30 years of leadership experience in the development and commercialization of biomaterials.  He previously co-founded EcoSynthetix in 1996, which held its IPO in 2011 (TSX: ECO), and was Canada’s largest IPO in the Cleantech sector.  In 2012, Steven received the Ernst and Young “2012 Entrepreneur of the Year Award”.  He helped prove out the base technology with pilot lines and production sites in the US and Europe and a manufacturing capacity for the starch nanoparticles in excess of 200 million lbs/yr.  He also built a broad global IP portfolio and established a broad network of university collaborators.  These collaborations using ECO’s biopolymer nanoparticles for dental and medical applications resulted in the foundational technology for GreenMark.  He is the inventor of over 25 patent families related to biomaterials.  He received his Ph.D. in Polymer Science and Engineering from the University of Waterloo.
