I use a multidisciplinary approach to enhance the growth rates, performance, and survival of animals. My goal is to prevent inefficiencies in agriculture and livestock operations while maximising cost-benefit outcomes. My research investigates the impact of nutrition on gut microbial populations, with a focus on its implications for the environment. Additionally, I am engaged in developing non-invasive and cost-effective tools and methods to optimise livestock production. Another area of great interest to me is fetal programming and development, specifically to investigate the impact of maternal nutrition on nutrient requirements, body composition, organ development, reproductive traits, microbial colonisation, growth performance, and the survival of their offspring. My research group strive to make significant contributions to the field of animal science by enhancing sustainability and efficiency of livestock production while fighting global warming.
