Role in the CAF-LTAR

As the lead of the WSU Farmers’ Network my work is focused towards stakeholder engagement through participatory co-innovation and the co-production of research. The Farmers’ Network partners with growers around the region in support of on-farm experimentation, and making connections with useful and usable applied agroecological research at the forefront.

Current Research Projects

  • Visualizing Microbial Agroecology (funded by WSARE)
  • On-Farm Experimentation
  • Soil Health Outreach
