Solomon Ajoseh-2.jpg

My name is Solomon Ajoseh, and I am from Nigeria. I hold an MSc in Agricultural Economics from the University of Florida, with a background in agribusiness management, supply chain analysis, and consumer behaviour.

My PhD research examines how farmers’ behaviour influences the effectiveness of vaccination and biosecurity efforts in controlling avian influenza. By exploring the real-world decisions farmers make, the project aims to support more effective disease control and inform evidence-based policies in the poultry sector.

I am based at Wageningen University and Research in the Netherlands, and my research is co-supervised by Dr. Jaap Sok, Dr. Armin Ruser, and Dr. Henk Hogeveen.

Outside of research, I enjoy playing football and participating in community outreach programs.

DC11 — Influence of farmer behaviour on the effectiveness of vaccination and biosecurity to control avian influenza

DC11 studies the human factor: which behavioural and economic drivers determine whether farmers vaccinate and maintain biosecurity—and how vaccination uptake might inadvertently relax biosecurity (“risk compensation”). Using stated-preference methods across diverse systems in the Netherlands and France, it quantifies preferences for vaccination program attributes.

By integrating these behavioural insights into quantitative risk assessment (with INRAE), DC11 shows how uptake patterns alter exposure risk at farm level. The results help design vaccination schemes that maximize compliance and effectiveness while avoiding unintended increases in infection risk.
