I  am passionate about Child and Adolescent /Youth Psychiatry research, clinical services and training and mentoring practitioners and scientists.

I established Wales' first academic Child and Adolescent Psychiatry/Youth Section and  direct it within the MRC Centre for Neuropsychiatric Genetics and Genomics and Division of Psychological Medicine and Clinical Neurosciences. I am clinically qualified. 

I am also a senior investigator in the National Centre for Mental Health (,Wales' first Biomedical Research Centre.

My research is developmental and focuses on adolescent depression,  irritability and neurodevelopmental disorders from 0 to 25 years.
