Associate Professor Marina Fortes

Primary research interest
Genetics, reproductive biology, and livestock sustainability
About me
I have a degree in Veterinary Medicine and a Master of Science in Animal Reproduction from the University of Sao Paulo (USP), Brazil. I completed my PhD in Genetics at The University of Queensland (UQ). After PhD, I worked as a post-doc at the Queensland Alliance for Agriculture and Food Innovation (QAAFI), gaining experience in genomics and cattle trials.
Now, I am an academic in the School of Chemistry and Molecular Biosciences. I teach genetics and genomics, and I lead the Livestock Genomics Group. As a research group, we are interested in understanding how genetics influence reproductive biology. Our research contributes to the development of sustainable livestock industry practices.
Research focus and collaborations
Livestock Genomics Group
Our Group investigates the genetics of livestock animals, applying genomic technologies. Beef cattle fertility phenotypes, which are complex and therefore influenced by multiple genes are our focus. Cattle fertility is a concern and an opportunity for improvement in Queensland's beef sector.
Imagine you have 100 cows, but they only produce 50-60 calves per year. An improved system would be to have 100 cows with higher genetic merit for fertility traits, which would produce 80-90 calves per year. Since the number of cows is the same in both scenarios (100) the environmental impact is similar, but more food is produced by the fertile cows. In short, our research aims at aiding the industry to produce more beef, and less methane.
Current projects in the group use genome-wide technology (i.e. SNP chips and Next Generation Sequencing) to investigate the genetics of female and male cattle fertility. We study puberty, spermatogenesis and fertility indicators such as scrotal circumference or length of post-partum anoestrus. The aim is to further understand reproductive biology and to create tools for genetic improvement towards higher herd fertility, translated into improved weaning rates.
Collaborative research expands the group activities and interests. Our group collaborates extensively with researchers at QAAFI, CSIRO Agriculture, and the Queensland Department of Ag and Fisheries to expand our capabilities. For example, we can now measure methane emissions using tracer gas methodology, which includes partnering with QASP at Gatton and AGFS for gas chromatography.

Researcher biography
Marina Fortes is an Associate Professor and Deputy Director for Agriculture in the Biotechnology program at The University of Queensland (UQ), where she leads the Livestock Genomics and Biotechnology Group. Her research focuses on applying genetics, genomics, and biotechnology to improve reproductive efficiency and sustainability in livestock systems. Her group integrates molecular biology, bioinformatics, and precision livestock technologies to address key challenges in the beef industry.
A major current focus of her research is understanding how physiological states, particularly pregnancy, influence enteric methane emissions, grazing behaviour, and metabolism in cattle. By combining field-based measurements with computational and genomic approaches, her work aims to improve carbon accounting methods and support the development of practical mitigation strategies for breeding herds, particularly in tropical production systems.
Marina holds a degree in Veterinary Medicine (2004) and a Master of Science in Animal Reproduction (2007) from the University of São Paulo, Brazil. She completed her PhD in Genetics in 2012 at UQ, supported by international scholarships from UQ and the Beef CRC, and received the Dean's Commendation for her thesis. She then undertook a postdoctoral position at the Queensland Alliance for Agriculture and Food Innovation (QAAFI), further developing her expertise in genomics and livestock systems. In August 2014, she joined the School of Chemistry and Molecular Biosciences (SCMB) at UQ, where she established her research group.
Her research program is strongly connected to industry and international collaborators, contributing to a dynamic and applied research environment aligned with sustainable livestock production. Her work has been consistently supported by Meat & Livestock Australia, and she was awarded an Advanced Queensland Fellowship (2018–2021) for her research on the genomics of cow fertility.
Marina is also actively involved in teaching and training the next generation of scientists, contributing to undergraduate and postgraduate courses, including Livestock Biotechnology (BIOT7038) within the Master of Biotechnology program. She co-produced the Women in Science podcast alongside Marloes Dekker and Kirsty Short, promoting the visibility and engagement of women in STEM.
