I have added significantly to the field of genomic research, both within psychiatric genomics and the wider genomics community, through valuable contributions to large multi-centre collaborations, my excellent research publication output, and the bioinformatics tools I have developed to improve our ability to study the effect of common and rare, protein-coding and regulatory variants. My work has led to a greater understanding of the types of genetic variants segregating in families and their possible functional roles in susceptibility to psychiatric illness and further underscored the lack of knowledge about the effects of genetic variants and the limitations of some of the sequencing technologies commonly used to fully describe the variation. I have extensive teaching experience and more than ten years PPI and science communication experience, including organising PPI events, scientific conferences and through my role as a member of the Outreach Committee for the Psychiatric Genomics Consortium (PGC) a global research initiative involving 900+ scientists.
