Derek is postdoctoral researcher at ILRI, specializing in modeling livestock systems and focusing on socioeconomic and environmental impacts. Using a systems approach, his models analyze synergies and trade-offs between livestock interventions. These models, serving as a foundation for user-friendly decision-making tools, inform stakeholders in policy, farm-level decisions, and Livestock Master Plans. Derek's research at ILRI has included studying the socioeconomic impacts of climate-smart agriculture technologies in Senegal, value chain impacts of a new slaughterhouse in The Gambia, meat demand characterization in Côte d'Ivoire, Nigeria, and Senegal, and exploring value chain upgrade opportunities in Tanzanian rangeland systems. He holds a PhD from McGill University in Montreal, Canada.
