Primary research interest

Genetics and reproductive biology

About me

I have a degree in Veterinary Medicine (2004) and a Master of Science (2007) in Animal Reproduction from the University of Sao Paulo (USP), Brazil. I completed my PhD in Genetics, in 2012 at The University of Queensland (UQ). After my PhD, I worked as a post-doc at the Queensland Alliance for Agriculture and Food Innovation (QAAFI), where I gained more experience in genomics and cattle trials. In August 2014, I joined the School of Chemistry and Molecular Biosciences. Now I am a senior lecturer in molecular genetics, bioinformatics and livestock biotechnologies. I am also the leader of the Livestock Genomics Group, and 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 develops genomic technologies applied to improve genetic gain for complex phenotypes. Beef cattle fertility phenotypes, which are complex and therefore influenced by multiple genes are our main 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; which would produce 80 calves per year. Since the number of cows is the same (100) the environmental impact is similar, but more food is produced. In short, we like to think of more beef, 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 and CSIRO Agriculture to further develop genomic selection approaches for beef cattle. Current collaborative research also includes genomic approaches to study chicken nutrition and growth. In another collaborative project, the genetics and proteomics associated with Human alcoholism are under investigation.

Researcher biography

Marina Fortes has a degree in Veterinary Medicine (2004) and a Master of Science in Animal Reproduction (2007) from the University of Sao Paulo, Brazil. She completed her PhD in genetics, in 2012 at The University of Queensland (UQ). For her PhD Marina had international scholarships from UQ and the Beef CRC. Her PhD received the Dean's commendation award. After that, Marina worked as a post-doc at the Queensland Alliance for Agriculture and Food Innovation (QAAFI). In August 2014, Marina joined the School of Chemistry and Molecular Biosciences (SCMB) as an academic and established the Livestock Genomics Group. As a researcher, Marina is interested in genetics and genomics, sustainable livestock production, and reproductive biology. Ongoing collaborations link her group to a rich research environment, both domestic and international, which contributes to sustainable livestock industries. Meat and Livestock Australia has provided ongoing support to the projects led by her group. For her work on the genomics of cow fertility, Marina received an Advanced Queensland Fellowship (2018-2021). Marina teaches undergraduate and postgraduate courses, including the Livestock Biotechnology course (BIOT7038) within the Master of Biotechnology program. The Women in Science podcast - https://soundcloud.com/womeninscience - was produced by Marina Fortes, Marloes Dekker, and Kirsty Short.
