Overview
I am an academic psychiatrist passionate about using genetic and big data approaches to enhance patient care. My research focuses on genetic factors and their influence on illness outcomes in severe mental illness. I believe in the importance of translating research findings into patient care, and I take pride in being part of the team behind the All Wales Psychiatric Genomics Service, the UK's first dedicated psychiatric genomics clinic.
I completed higher psychiatry training in General Adult Psychiatry in South East Wales, with a subspecialty endorsement in Rehabilitation Psychiatry.

Research
My research focuses on genetic factors and their influence on illness outcomes in severe mental illness. I believe in the importance of translating research findings into patient care, and I take pride in being part of the team behind the All Wales Psychiatric Genomics Service, the UK's first dedicated psychiatric genomics clinic.
Teaching
I teach psychiatry on the Cardiff University Medicine MBBCh course, including small group teaching on suicide and self harm and communication skills. I also examine formative and summative psychiatry ISCE examinations. I am an academic mentor to students on the course and I'm involved in peer review for scientific journals.
