Guests


Professor Moira O'Bryan

Prof O’Bryan is a reproductive biologist with expertise in the area of fundamental mechanisms required to produce fertile sperm, the causes of male infertility and the role of sperm structure-function as a driver of evolution. Areas of particular emphasis of her laboratory include the mechanisms of sperm head shaping and cilia/flagellar development and function, genetic causes of human infertility, the importance of epigenetic regulation in male fertility and transgenerational health, and the connection between male fertility and overall health – a concept often referred to as ‘the canary in the coalmine hypothesis’. To achieve these aims, her laboratory uses a range of animal and cell models, high end imaging technologies and suites of biochemical and cell biology approaches.

Prof. O’Bryan is the Dean of Science at the University of Melbourne. She currently sits on the editorial boards of Molecular Human Reproduction, Andrology and PLOS Genetics. She, along with Prof. Rob McLachlan from the Hudson Institute of Medical Research, run the Monash Male Infertility Repository. She is also a past President of the Society of Reproductive Biology and has received numerous awards for her contributions to the field of reproductive biology.


Early Career Researcher Spotlight


Dr Natalie Trigg

Natalie received her Bachelor of Biotechnology (Honours) (2016) and PhD (2021) from the University of Newcastle, Australia. During her PhD Natalie investigated the impact of paternal environmental exposure on the sperm small RNA profile. Specifically, her research investigated the impact of exposure to the xenobiotic, acrylamide during epididymal transit, on the sperm small RNA profile and how exposure mediates changes in the sperm small RNA profile and the consequences to embryo gene expression. Now as a postdoctoral research fellow at the University of Pennsylvania and Children’s Hospital of Philadelphia Natalie’s research focus lies in uncovering the cellular functions of epididymal acquired sperm small RNAs after fertilization.
