Dr Elham (Ellie) Assadi Soumeh is a Senior Lecturer in Animal Science and Production at the School of Agriculture and Food Science, University of Queensland. She holds a BSc in Animal Science, an MSc in Animal Nutrition, and a PhD in Animal Nutrition and Physiology, with a focus on monogastric species, particularly poultry and swine.

Dr Soumeh completed her PhD at Aarhus University in Denmark, where her research focused on the requirements and metabolism of branched-chain amino acids (BCAAs) in weaned pigs and the metabolic profiling of high-performing pigs fed optimal BCAA levels. Following her PhD, she worked as a Senior Scientist at Cargill BV in the Netherlands, leading customer-focused research in monogastric nutrition. Her work there spanned nutrient metabolism, gut health, and nutritional strategies aimed at improving production efficiency.

Her current research explores the role of nutrition in modulating gut microbiota composition and function, and how these microbial shifts influence host metabolism, health, and productivity. She is particularly interested in the interplay between dietary components, gut microbial ecology, and the physiological responses of monogastric animals.

Dr Soumeh's work addresses practical and emerging challenges in animal nutrition, with an emphasis on sustainable feeding practices and precision nutrition. Her research findings have been widely published in high-impact scientific journals and presented at leading international conferences and symposiums.

Kieren McCosker has expertise in tropical beef production. Kieren completed an Agriculture Science - Animal Science degree (University of Queensland) and later a PhD (School of Veterinary Science, University of Queensland) deteriming the factors associated with reproductive performance in northern Australia beef cows, otherwise known as the Cash Cow project while working in the Agriculture Division of the Northern Territory Government's Department of Industry, Tourism and Trade. In 2021, Kieren commenced working with the Centre of Animal Science, Queensland Alliance for Agriculture, Food and Innovation and comes with approximately 20 years of experience investigating production issues across many facets of the northern beef production system and south-east Asia. Some of his current projects examine the impact of shade and paddock infrastructure on calf mortality, and utilising remote technologies to remotely detect key production events, such as calving and associated maternal behaviours.

I study aspects of reproductive physiology that impact fertility in cattle, early embryonic development, and precision animal agriculture technologies that can improve animal health and performance. The goal of my research program is to apply research-based knowledge to refine current and develop new bio-technologies that can be readily adopted by cattlemen.

My research program is centered on three focus areas:

1. To investigate reproductive physiology and advance reproductive efficiency of beef cattle through the development of reliable bio-technologies that can be quickly implemented;
2. To maintain collaborative research that focuses on investigating early embryonic development in cattle;
3. To develop reliable, efficient, and profitable management strategies and technologies that can enhance the productivity of beef production systems.

Dr Taylor Pini is a lecturer in veterinary reproduction within the School of Veterinary Science and leads the Molecular Animal Reproductive Biology Lab (MARBL). Taylor's research focuses on understanding fundamental reproductive biology across species, in order to improve the outcomes of assisted reproductive technologies (ARTs) like artificial insemination for livestock and wildlife. Some recent examples of her research work include:

• Exploring sperm formation and function in kangaroos
• How cooling and freezing sperm impacts cellular 'clean up' machinery
• Why frozen ram semen fails to get ewes pregnant
• How the cellular makeup of sperm differs across the kingdom of life

Taylor graduated with a Bachelor of Animal and Veterinary Bioscience (Hons) and a PhD in reproductive biology from The University of Sydney. After her PhD, Taylor undertook postdocs at the Colorado Center for Reproductive Medicine (USA), and with the Gametic Epigenetics Consortium against Obesity (GECKO) at The University of Sydney, before beginning at UQ in 2021. Taylor has worked across many aspects of reproduction (from pregnancy detection to sperm freezing) in a range of species, including mice, humans, sheep, horses, koalas, kangaroos, parrots and echidnas.

Taylor is a co-host and producer of the science communication podcast Repro Radio.

Looking for a research project? Taylor is currently on parental leave, but will be taking on Summer and Winter Scholarship Students (undergraduate), Science Honours Students, Masters and PhD students in 2027.
