Dr. Peter Ako Larbi has been an Assistant Cooperative Extension Specialist in Agricultural Application Engineering with the University of California, Division of Agriculture and Natural Resources (UC ANR), since 2018, and a faculty member with the Department of Biological and Agricultural Engineering at University of California Davis (UC-Davis) since 2019. He is based at the Kearney Agricultural Research and Extension Center in Parlier. As part of his research and extension program, his focus is on developing and promoting best practices for safe, economical, and environmentally sound pesticide application with reduced environmental risks.

Prior to joining UC ANR, Dr. Larbi had been an Assistant Professor of Agricultural Systems Technology in the College of Agriculture at Arkansas State University since 2014. He developed an integrated teaching and research program related to agricultural systems technology; developed and managed research in precision agriculture, agricultural machinery systems, remote sensing and sensor technology; and provided service to the university, college, local community and general scientific community. He held a joint appointment in the Division of Agriculture at University of Arkansas.

From 2012 to 2014, Dr. Larbi was a postdoctoral research associate at the Center for Precision and Automated Agricultural Systems at Washington State University. From 2011 to 2012, he was a postdoctoral researcher at the University of Florida Citrus Research and Education Center.

Dr. Larbi earned a Ph.D. in agricultural and biological engineering from University of Florida, and a M.Sc. and a B.Sc. in agricultural engineering from the Kwame Nkrumah University of Science and Technology in Kumasi, Ghana.
