Personal profile
Research interests
My research interests include using longitudinal datasets to investigate mental health, cognitive function and other psychological factors from childhood through to adulthood.
I currently work as a Research Associate on an international project investigating multi-informant (i.e, parent and teacher) perspectives of adaptive functioning, mental health and autistic traits in a cohort of autistic children.
I completed my PhD in the Addiction and Mental Health group, investigating cannabis use disorder in adolescents and young people, including identifying predictors of problematic cannabis use, as well as evaluating available treatments.
I use quantitative data analysis methods such as latent class analysis and mixed effects models, working primarily with R, STATA, and Mplus.
