Hiroyuki Takeshima joined IFPRI in January 2009 as a postdoctoral fellow of IFPRI Nigeria office, and joined IFPRI Washington office as a research fellow in 2012. Hiroyuki has conducted research on market participation, transaction costs, agricultural technology adoption, biodiversity, and political economy of seed policies in sub-Saharan Africa. His recent research also focuses on the linkages between market and climatic risks and farmers’ investment, roles of modern production technologies such as irrigation, mechanization, fertilizer on agricultural transformation in sub-Saharan Africa.

Hiroyuki earned his PhD from Agricultural and Consumer Economics from University of Illinois, Urbana-Champaign in 2008. Hiroyuki is a citizen of Japan.
