Thereafter she pursued postgraduate studies, obtaining her PhD from the University of Glasgow in 1989. She then spent four years at the University of Manitoba, Canada, initially as a post-doctoral fellow and then as a faculty member.

In September 2022 she retired from her post as Professor of Dental Public Health at the University of Glasgow and Honorary Consultant in Dental Public Health for NHS Greater Glasgow and Clyde.

She is involved in the development and evaluation of complex public health interventions, with a particular focus on child oral health. Her research includes clinical trials, cohort studies and natural experiments and utilises data linkage. Until her retirement she was Co-Director of the Scottish Government’s child oral health improvement programme (Childsmile) and she is still involved in advising overseas agencies and governments on the development and evaluation of similar initiatives.
