David completed his Ph.D (2012) at the Institute of Psychiatry, King’s College London, where he performed in-depth functional genetic characterisation of two novel loci implicated in alcohol consumption following a large-scale meta-analysis of genome-wide association study (GWAS) data. Following this, David accepted a position at the University of Adelaide working as a Post-Doctoral researcher and Lecturer, where he obtained funding as a new investigator to apply next generation RNA sequencing technology within the context of Major Depressive Disorder (MDD) and Bipolar Affective Disorder (BPAD) patients. David joined the Cardiovascular Epidemiology Unit (CEU) in February 2016 as a functional geneticist, with a primary interest in following up on complex disease-related GWAS hits to elucidate the molecular mechanisms and biological processes mediating their impact on disease.
Given the ever-increasing number of genetic loci being implicated in the regulation of complex human disease, determining precisely how these polymorphic loci impact on disease represents a major bottleneck constraining the translation of GWAS findings to diagnostic and therapeutic clinical applicability. Accordingly, David’s main research interests relate to:
1. How sequence or structural genetic variation impacts upon gene function
2. The use of recall-by-genotype studies to elucidate the molecular mechanisms mediating genetic associations with coronary artery disease
3. Genetic control of the proteome and the metabolome
4. The application of functional genomic approaches, particularly those involving next generation sequencing technologies, to investigate how the regulation of mRNA expression, splicing, and editing might alter disease susceptibility and treatment response
5. Applying network-based approaches such as weighted gene co-expression network analysis (WGCNA) to obtain a systems view of disease mechanisms and to identify clusters – or modules – of functionally related genes involved in disease pathophysiology
