Dr. John Ojiem holds a PhD in Soil Science from Wageningen University and Research Centre, The Netherlands. He is currently the Centre Director of Kibos Research Centre, one of the Kenya Agricultural and Livestock Research Organization’s centres situated in Kisumu, western Kenya. Dr. Ojiem is the Project’s Principal Investigator and leads an interdisciplinary team of researchers spearheading the integration of multipurpose grain legumes into western Kenya smallholder systems to reinvigorate the systems and improve system health and productivity.
