Since 2014 she has been the Principal Investigator of the Millennium Cohort Study, a major nationally representative longitudinal study following over 19,000 children born at the turn of the millennium. Her research is focused on understanding and evidencing the early emergence of inequalities and their influence on outcomes and experiences, both in childhood and adulthood. Recent work includes the impact of breastfeeding on children’s cognitive development and health, and the long-term implications of early cognitive and socio-emotional inequalities for adult outcomes. She has expertise in quantitative methods drawn from econometrics and other quantitative social science disciplines, and is particularly interested in the application of methods that strengthen causal identification.
