    After this she moved into general adult psychiatry, working predominantly in Barnet as a staff grade for the Crisis Intervention Service and in forensics as part of the Mentally Disordered Offenders team. An interest in management and business led her to complete her MBA at INSEAD (France) followed by a few years in property management/development both in France and South Africa as well as in medical aesthetics.

    The theme of transformation led her back into psychiatry, this time into addictions, where she found her niche. Her particular area of interest is the significant and complex link between neurodiversity and addiction.
