Leesa Dunstan is a Research Officer at Adelaide University, based at Roseworthy Campus. Leesa has a strong interest in bridging the gap between research, industry, and producers—ensuring that scientific innovation translates into real-world impact for agriculture.
Her current research focuses on testing current industry available products used to reduce enteric methane emissions with other potential solutions to support sustainable livestock production. Alongside her role, she is also in the final stages of her PhD, investigating fetal programming effects of amino acid supplementation in multiple-bearing ewes to improve lamb productivity and survival. This work combines physiology, nutrition, and management practices to enhance on-farm outcomes.
