Associate Professor Geoff De Iuliis completed his PhD in Chemistry at the University of Newcastle, and while staying on in Newcastle, he switched fields to begin a career investigating male infertility. Those early interests centred on how oxidative stress is generated in spermatozoa and how this leads to cellular damage, loss of sperm function and the induction of paternal DNA damage. While these insights have been important in opening avenues for future IVF technologies, there are still many fundamental things about sperm cells and the male reproductive system, we are yet to uncover. Associate Professor De Iuliis and the research team are currently designing much needed technologies for selecting the best possible sperm for ‘IVF’ and also driving forward our understanding of how environmental factors such as ‘PFAS’ and wireless communication electromagnetic energies can impact male reproduction and offspring health.
