Professor John O Doherty is a leading authority in Animal Science, serving at University College Dublin. His pioneering work focuses on transforming monogastric systems to achieve greater sustainability. By blending expertise in animal nutrition with a deep understanding of environmental challenges, he explores innovative strategies that not only bolster animal resilience to pathogens but also minimise the ecological footprint of livestock production. Central to his approach is the integration of advanced technologies, including genomics. These tools empower him to precisely evaluate and forecast the effects of tailored feeding regimens and environmental conditions on livestock performance. His holistic vision and groundbreaking research contribute profoundly to redefining sustainable agriculture, ensuring it meets the demands of a growing global population while safeguarding the planet’s resources.
