Ashley is a National Heart Foundation Postdoctoral Fellow in the Early Origins of Adult Health Research Group. His research focuses on two main areas: 1) understanding and targeting androgen signalling in pregnancy to improve generational cardiometabolic outcomes; 2) exploring the impact of pregnancy complications on drug metabolism in the maternal, placental, and fetal compartments. Through his research, Ashley hopes to improve the efficacy and safety of drugs commonly used during pregnancy, and develop novel diagnostics and interventions to ensure that every baby gets the most out of life.
