School of Psychology


Melbourne Burwood Campus



Dr Youssef is a cognitive neuropsychologist and biostatistician with expertise in the design and analysis of longitudinal studies of socioemotional and neurocognitive development, spanning childhood through to adulthood.

Biography summary

Dr Youssef completed his PhD and Master of Psychology (Clinical Neuropsychology) degrees in 2013 (University of Melbourne) and Master of Biostatistics degree in 2015 (University of Melbourne). He was previously employed as a research fellow at Monash University and worked clinically in the neuropsychology team at the McKellar Center (Barwon Health). Dr Youssef was offered a continuing appointment at Deakin University in 2015. He is a senior member of the Data Sciences Platform within the Centre for Social and Early Emotional Development (SEED) at Deakin University and leads the Longitidinal and Cohort Studies Group which provides statistical consulting support to all longitudinal studies within SEED. He holds an Honorary appointment in the Centre for Adolescent Health at the Murdoch Childrens Research Institute.

In the years since completing his PhD, Dr Youssef's research has been primarily focused on quantitative psychology and statistical consulting work across a number of major (i.e. ARC and NHMRC funded) longitudinal studies of development in Australia. He is a senior statistical advisor for the Australian Temperament Project, one of the oldest studies of development in Australia, spaning 35+ years and three generations of participants (n=2400); the Adolescent Development Study, which is a large longitudinal study of adolescent neurobiological and socioemotional development (n=400); and the Triple B Pregnancy Cohort Study, which is examining how perinatal factors influence development over time (n=1600). He is also an investigator on a major ARC funded project focussed on cross-cohort analysis of major longitudinal intergenerational studies (Australian and New Zealand Intergenerational Cohort Consortium) and is an active analyst within other major consortiums focused on the cross-cohort analysis of longitudinal data across Australia and New Zealand (e.g., Cannabis Cohorts Research Consortium). Finally, he is the senior statistical advisor for the Gambling Studies group at Deakin University (embedded within the Deakin University Centre for Drug use, Addictive and Anti-social behaviour Research; CEDAAR) and in this role has made substantial contributions to major government funded (e.g. Victorian Responsible Gambling Foundation, Tasmanian Department of Treasury and Finance) studies of gambling behaviour, which have direct implications for the public (e.g., developing empirically derived responsible gambling guidelines for the Victorian Government). Beyond quantiative methods, Dr Youssef has specific interest in risk taking and exploratory behaviours and leads a program of research examining the development and phenomenology of these behaviours over the lifecourse.
