Research summary
Assigning function to genetic variants associated with metabolic traits

Research

My research projects aim to assign function to genetic variants that are associated with health and disease using bioinformatics, zebrafish and cell assays. I also work with Māori and Pacific genetic data to identify clinically-relevant genetic variants that are unique to Māori and Pacific people. The long-term outcomes of this work has the potential to reduce health disparities and improve genetic equity in these population groups.
