Developmental Neuroscience

Cognitive and Behavioural Neuroscience

Interests

Having trained as an experimental (B.Sc., PhD) and applied psychologist (Dip.App.Psych.) and in Health Services Research / Health Technology Assessment (M.Sc.) I am principally involved in a quantitative role in the design and analysis of epidemiological cohort studies and psychometric or biostatistical analysis. I make use of modern latent variable and item response theory methods and comprehensive structural equation modelling frameworks (Mplus and Stata gllamm procedures or equivalents and therefore characterise my work as Psychometric Epidemiology (following Muthen). I collaborate with five birth cohort studies in the UK and elsewhere, the MRC Biostatistics Unit and psychiatric and psychological researchers. In Cambridge I continue to work on psychosis and in conjunction with Ian Goodyer I am developing aetiological/prediction models for adolescent affective disorder.
