  • Senior Sustainability Scientist, Global Institute of Sustainability and Innovation
  • Program Manager, Sustainable Phosphorus Alliance


Matt manages operations at the Sustainable Phosphorus Alliance, which is a multi-stakeholder effort to promote the efficient use, recovery, and recycling of the key nutrient phosphorus in the food system. He works with organizations across the phosphorus value chain and across industrial sectors to implement more sustainable phosphorus management practices. Prior to joining the Alliance, he served as a Senior Research Scientist for The Sustainability Consortium, where his work focused on developing metrics used by retailers to assess the sustainability of their supply chains.

Matt did his postdoc in Chemistry at Colorado School of Mines and worked on projects for the Sustainable Algal Biofuels Consortium. He received his PhD in Agricultural and Biosystems Engineering (2011) and MS in Chemical and Environmental Engineering (2001) from the University of Arizona, where he also worked for 6 years as a molecular biologist. Matt contributed to the development of Equitable Origin's EO100 Standard for energy development projects, previously chaired the county Green Party in Tucson (2000), and was a member of the Green Fund Committee that oversees sustainability efforts at the University of Arizona. He oversees the annual Phosphorus Forum conferences and has run numerous workshops, panels, and field tours on sustainability, including presentations at GreenBiz and the PEF World Forum.
