Hossein Zakeri

Assistant Professor

Personal Information

Hossein Zakeri came to Chico from the University of Missouri where he was postdoctoral fellow studying soybean water use efficiency. He has a PhD in the field of crop physiology and cropping systems from the University of Saskatchewan. Hossein’s work and research focuses on row crops. He has done research on safflower, wheat, lentil, pea, canola and soybean. For his PhD, he studied nitrogen acquisition and biological nitrogen fixation of lentil. After his PhD, Hossein worked for Crop Development Centre and Agriculture and Agri-food Canada studying pulse crops nodulation, pea nitrogen fixation, and canola water use efficiency and drought tolerance mechanisms. Hossein has a BS in agronomy and crop breeding and an MS in crop physiology from Iran, where he also taught undergraduate agriculture during 1999 – 2006.
