Our Team

The California Nitrogen Assessment is led by four principal investigators – Thomas P. Tomich, Daniel Sumner, Kate M. Scow, and Randy Dahlgren – professors at the University of California, Davis. Additional project staff includes three post-doctoral research fellows, one communications and outreach fellow, and academic and communications coordinators. A distinguished nine-member technical advisory committee provides oversight for the project, a stakeholder advisory board provides comment and review from stakeholder perspectives, and an eight-member multidisciplinary faculty workgroup on nitrogen science and agriculture conducts complementary research.
