Matthew Klein, M.S., is a Ph.D. student in the Mitloehner Lab at University of California, Davis, with diverse research interests related to beef cattle production. Topics of interest include: further determining the role of cattle in climate change, effective maintenance of grazing lands, and addressing issues at the nexus of science and policy.

Matthew has previous research experience in forage and seed crop production, insect pest management, and soil science. He arrived at UC Davis with a desire to continue expanding his ability to conduct top quality research related to key problems in agriculture. Matthew enjoys collaborating and connecting across disciplines and sees taking an integrative approach as crucial to solving problems of increasing complexity.

Outside of academia, Matthew enjoys practicing guitar, rock climbing, and reading.
