Professor Sarah Robertson is a world-renowned reproductive scientist whose innovative work on cytokines and immune cells underlies advanced understanding of the origins of health at conception. She has demonstrated that cytokines and immune cells regulate embryo implantation and development, and that seminal fluid contributes to the immune changes that promote female receptivity to pregnancy. Her work shows that the immune system channels environmental signals from both parents to contribute to healthy pregnancy and shaping offspring phenotype after birth. She is a public advocate of reproductive health and her discoveries are improving reproductive medicine and providing insight into early determinants of child health.
