Profile Summary

Eduard Roos is a passionate wildlife researcher, dedicated to the One Health approach, which integrates human and veterinary medicine to tackle zoonotic diseases and support wildlife conservation across Africa. His academic journey began with a BSc in Zoology at the University of Pretoria, followed by a BSc Honours in Molecular Parasitology at the University of the Free State, where his interest in molecular biology and host-parasite interactions deepened. He completed a PhD at Stellenbosch University, focusing on molecular diagnostics for Mycobacterium bovis (bovine tuberculosis) in warthogs, advancing both diagnostic techniques and the understanding of M. bovis phylogenetics in wildlife. Eduard has worked at The Pirbright Institute in the UK, specializing in immunophenotyping and diagnostic development for livestock diseases, and at Clinomics (Pty) Ltd, focusing on molecular diagnostics for animal health. Currently, he serves as a Lecturer in Wildlife Health and Immunology at the Royal Veterinary College, where he combines his expertise with practical applications in wildlife disease research. His work emphasizes the interconnectedness of human and veterinary health, contributing to disease control and conservation efforts.
