Summary
👤
Senior🎓
Top SchoolDuncan Bellamy is a vaccine product development leader and vaccinologist with eight years’ experience spanning academia, biotech and global health philanthropy, including a PhD from Oxford and roles supporting licensure of R21 malaria and Oxford/AstraZeneca COVID-19 vaccines. He combines hands-on immunology and clinical-trial coordination expertise with experience in assay development, sample processing and cross-site trial setup in the UK and West Africa. At Recursion he translated immunology insights into target validation assays, and at Wellcome Trust he now focuses on translating technical evidence into strategic product and policy decisions. He brings a proven track record of managing complex phase II–III trial workflows, training local teams, and ensuring regulatory-grade data generation. Unusually for a vaccinologist, he also contributes to performance-critical open-source backend projects (Ceph, Seastar, rspamd), reflecting strong systems thinking and portability-focused coding skills. He is now seeking commercial, policy or consultancy roles where technical depth informs strategic impact on public health.
