Overview
My research is based around the role of genetic factors in the development of psychiatric disorders. Within the Centre for Neuropsychiatric Genetics and Genomics, I work with Professor James Walters and others on treatment-resistant schizophrenia (TRS), widely recognised as the most impairing form of this disorder and a significant global contributor to years lived with disability. I am a member of the Psychosis Research Theme and am involved in several of its projects, collaborating frequently with the Schizophrenia Working Group of the Psychiatric Genomics Consortium.

Research
I led an Academy of Medical Sciences Springboard Award on "Pharmacogenomics of Antipsychotic Treatment and Response" (PATRON, 2020-2023), focused on the antipsychotic clozapine. Clozapine is the only drug licensed in the UK for treatment-resistant forms of schizophrenia. While it is known to improve the symptoms of many individuals, is also underprescribed and often discontinued early on the basis of poor efficacy or adverse side effects. With PATRON we sought to conduct basic research to understand why this happens, hopefully leading to evidence that will be used in the future to improve the effectiveness of clozapine. You can read about a representative PATRON publication here.
I am currently involved in further work related to clozapine and treatment resistance in psychiatric disorders, mainly within the EU-funded project PsychSTRATA (2022-2027) and the UKRI-funded project GENios (2024-2029). I am also a co-investigator and Data Quality and Integrity Lead of the Brain and Genomics Hub project (2024-2029), as well as Data Lead for Cardiff University at the National Centre for Mental Health.
I am Principal Investigator of the Wellcome-funded SYLFAEN-PSY project (2026-2028).
Researchers can find open access data related to my projects in the Walters Group website.
