For more than 30 years, he has focused on impactful and inclusive seed systems research for development, technology delivery systems and research product commercialization and wider utilization. He has contributed to and led various research for development projects in agricultural research areas, including participatory crop research in partnership with value chain actors and building partnerships to commercialize and scale up proven technologies including farmer & consumer demanded and climate resilient varieties. For the last 20 years, he has been the Seed Systems Specialist at PABRA and has led multi-country public private partnership initiatives and multi-disciplinary teams developing and deploying sustainable and impact-oriented bean seed systems and complementary management to reach more than 35 million smallholder farmers (58.5% being women) across PABRA member countries.
