Professor Nathan's research activity has mirrored his clinical career. Thus for more than ten years he has been involved in research in the area of forensic practice with a particular interest in (i) personality disorder in forensic settings, (ii) psychological processes underpinning violence and antisocial behaviour, and (iii) applied research in clinical settings.

He was part of a multicenter research team which undertook an RCT of a complex intervention for high risk personality disordered offenders in the community.
