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.
