I am a quantitative sociologist with a particular interest in using administrative and birth cohort data to explore various aspects of child development, primarily of children with some sort of vulnerability e.g. they were exposed to opioids during pregnancy, have a neurodevelopmental disorder or were maltreated in the early years. I have a BA (hons.) in Politics and Sociology, and a MA in Research Methods, both from Durham University, and a Ph.D. in Psychological Medicine from the University of Glasgow. 

I spent several years working for the National Centre for Social Research, working mostly on the Growing Up in Scotland study (Scotland’s national birth cohort study), as well as working on various other projects including the Scottish Health Survey and the evaluation of the Family Nurse Partnership pilot. Following this I undertook my PhD in the Department of Child and Family Psychiatry, University of Glasgow, exploring the impact of schools on the development of early mental health difficulties, using routinely collected data from Glasgow city schools. After my PhD I undertook postdoctoral positions in the School of Mathematics and Statistics, and Department of Child and Family Psychiatry, both at the University of Glasgow, and then the Scottish Collaboration of Public Health Research and Policy, and the Salvesen Mindroom Research Centre, both at the University of Edinburgh.  

I enjoy undertaking public engagement activities and I am currently the School of Health Sciences Lead for Public Engagement, Enterprise and Impact.


In 2020 I joined the Mother, Infant and Child Research Group at the University of Dundee as a Baxter Fellow. I was awarded an ESRC New Investigator Grant in 2020 to explore the impact of opioids on children’s early health development using Scottish data. In 2024 I was awarded a UKRI Future Leaders Fellowship to investigate the impact of exposure to opioids in pregnancy on health, education and justice outcomes up to the age of 16 using UK and international datasets.
