Dr Natalie Trigg earned her PhD in 2021 from the University of Newcastle under Prof. Brett Nixon, studying the dynamics of sperm small RNAs and sperm-extracellular vesicle communication. Dr Trigg was then recruited to A/Prof. Colin Conine’s lab at the Children’s Hospital of Philadelphia, USA where she identified the acquisition of a subset of microRNAs by sperm during epididymal transit and uncovered their function post-fertilization. Now a postdoctoral researcher at the Hunter Medical Research Institute’s Infertility and Reproduction Program, Dr Trigg focuses on how sperm RNAs influence male fertility, embryo development, and offspring health contributing to our understanding of the importance of the paternal preconception period.
