Graeme Martin has studied livestock physiology and behaviour for 40 years, in Australia, France, Scotland, Mexico, and other countries. He has been particularly interested in how environmental factors (nutrition, pheromones, stress) affect reproduction. He harnesses the world’s knowledge in this field to develop animal management systems that are ‘clean, green and ethical’. In 2019, he was elected to the Academie d’Agriculture de France and, for 2021, he has been awarded the Marshall Medal from the Society for Reproduction and Fertility, the UK society’s highest honour, and a Fellowship in the Australian Association of Animal Sciences.
