Hossein Zakeri

Associate Professor

Personal Information

Hossein Zakeri has a Ph.D. in the field of crop physiology and cropping systems from the University of Saskatchewan. For his Ph.D., he studied nitrogen acquisition and biological nitrogen fixation of lentil. After his Ph.D., Hossein worked for the Crop Development Centre and Agriculture and Agri-food Canada and studied pulse crops nitrogen fixation, and canola water use efficiency, and drought tolerance mechanisms. He then moved to the University of Missouri, where he studied water use efficiency of domesticated and wild soybeans. His current research focuses on fava bean as a food and cover crop in the Western United States. Hossein has a BSc in agronomy and crop breeding and an MSc in crop physiology from Iran, where he also taught undergraduate agriculture during 1999 – 2006.
