Prakash joined IRRI in May 2015 as an agricultural economist and currently leads the social science activities in South Asia. His team is involved in rice varietal tracking and identification, adoption and impact assessment of stress tolerant varieties, developing premium rice value chains and business model development for service delivery in the rice farming system. He is involved in bilateral projects such as Rice Monitoring System in South Asia (RMS-SA), Cereal System Initiative for Sustainable Intensification (CSISA) and Stress Tolerant Rice for Africa and South Asia (STRASA).  Before joining IRRI, he was working at GlobalFood group, University of Goettingen, Germany where his primary focus was on analysing producer preferences and participation of smallholders to modern market value chains. The analysis involves gendered preferences for certification standards among small producers and vegetable suppliers of supermarkets. Recent research works in IRRI centred on preference analysis of rice seed producers and consumers, caste and social networks, varietal adoption and turn over, information and technology adoption, hypothetical bias, measurement error in agricultural surveys, crop insurance choice and premium rice value chains.
