My research investigates how everyday exposure to bisphenols (BPA and BPS) found in food and drink packaging impacts oocyte quality and female fertility. Being among the longest-lived cells in the body, oocytes are particularly vulnerable to cumulative damage from harmful dietary exposures, yet in Australia bisphenols remain minimally regulated, with the 'safe' daily intake for BPA set 250,000 times higher than in Europe. Using a rigorously controlled mouse model, my current work aims to understand the impact of low-level dietary exposure to BPA and BPS on key markers of ovarian health, oocyte quality, and more broadly, reproductive health. Through this work, I aim to generate robust causal evidence to help drive policy changes and better regulations to safeguard fertility against dietary contaminant exposures. Alongside the science, I will reflect on my journey in research so far, including the key experiences that have shaped and continue to shape my path as an early career researcher, and the role of identity in building a research career and navigating academia.
