My PhD project, titled Large-scale cognitive and genetic investigations into the relationship between infant temperament and later mental health outcomes will use data from a number of different pregnancy and birth cohorts from the EArly Genetics and Lifecourse Epidemiology consortium (https://www.eagle-consortium.org/) to map the common genetic architecture of infant temperament traits. The project will also look into the role of infant temperament on lifespan development at behavioural and cognitive levels using longitudinal research designs. It is part of the Genetics of Early Milestones and Skills project (GEMS).
