On 16 November 2015, Brown launched the Theirworld Birth Cohort project, a £1.5million study aimed at improving the health of women and their children who are born prematurely, at Edinburgh University as part of the Jennifer Brown Research Laboratory. The project will track the development of 400 babies, most of whom are born before 32 weeks, following them through to adulthood, tracking educational attainment to help identify the causes and consequences of brain injury at birth and help speed the development of new treatments that could improve the health of prematurely born babies.
