Oli G. Bachie is currently the University of California Cooperative Extension (UCCE) Agronomy Advisor for Imperial, Riverside and San Diego counties. He is based in the UCCE office in Imperial. His research focus is primarily, but not limited to crops such as alfalfa, wheat, sudangrass, Bermudagrass, Kleingrass, cotton, sugar beets, and bioenergy crops and their cropping systems.

Bachie earned his Ph.D. in Plant Biology at University of California Riverside (UCR) and has worked as an Assistant Research Specialist in the UCR Department of Nematology before coming to the UCCE Imperial office. His dissertation research explored Interdisciplinary pest management (insects, nematodes and weeds) potentials of cover cropping systems. He has also earned a Master’s degree in Forestry (MScF) from the University of Toronto, a Master’s degree in Agronomy (MSc) from the University of the Philippines and a Bachelor degree in Plant Sciences (BSc) from Haromaya University (Ethiopia).

Bachie has worked as an adjunct professor of network administration and Computer Architecture at National University and American University in San Diego, as research specialist at the San Diego State Universities and as an adjunct professor of Biology at the Victor Valley College (VVC) for over six years. He currently teaches agricultural courses as part time at the Imperial Valley College. He is the current chairperson for the Research Advisory Committee (RAC) for the Desert Research and Extension Center (DREC).

Prior to moving to North America, Bachie worked at the Ministry of Agriculture in Ethiopia as an expert in crop protection, crop production and weed management.

Bachie provides research-based technical and educational assistance in agronomy and sustainable agriculture to agricultural producers, growers, farm operators, pest control advisors (PCAs) and other agricultural clientele in Imperial Valley, San Diego and Riverside counties. He develops and encourages adoption of research based cropping systems to improve crop productivity and yield with due consideration for environmental and ecological compatibility.

Bachie is a good standing member of the American Society of Agronomy (ASA), the Desert workgroup, University of California (co-chair), the Alfalfa and Forage workgroup and the Western Society of Weed Sciences (WSWS). .
