Researcher biography
As a Senior Lecturer in Animal Science and Production, my research focuses on nutrition and gut microbiology. I completed my Ph.D. through the University of Sydney investigating the effects of various feed additives on performance, and meat quality of sheep. I then went on to complete a Post-doctoral Fellowship in Canada (The University of Alberta), investigating the effects of weaning age and strategy on the development of the ruminal microbiome in dairy calves. Developing this research theme, I was awarded a highly prestigious Marie-Curie Individual Fellowship for a 2-year project in France, to investigate the effects of additives on gut microbiome establishment and programming for lifelong effects in dairy calves to reduce methane emissions. In October 2017, I began my current position as a teaching and research academic at The University of Queensland focusing on feed efficiency, and environmentally sustainable ruminant production systems with a focus on manipulating the rumen for reduced methane emissions and enhanced production. I bring a multidisciplinary approach to my research to examine the effects of nutrition and age on microbiology, production performance and meat quality of an animal.
