 I am passionate about understanding the mechanisms underlying poor oocyte quality that will allow for the development of fertility treatments and diagnostics.

I completed three years of postdoctoral training at the University of Edinburgh (2022), where I studied mechanisms that drive aneuploidy in human eggs and embryos. I previously completed my PhD at the University of Newcastle (2019), which focused on the impact of oxidative stress and epigenetics on the age-related deterioration of the mammalian egg. I then completed a year of Postdoctoral training (2019), where I studied oocyte development and growth during folliculogenesis and chronic chlamydia infection.

I am currently working on strategies to improve age-related fertility. I am investigating the relationship between altered oocyte metabolism and the age-related decline in egg quality. I aim to investigate how metabolic supplementation can improve chromosome segregation and ultimately improve the fertility of older women.
