PhD (VUW), MBmedSc (VUW), BSc (Massey)
Background
I completed both my Masters and PhD in Biomedical Science through Victoria University of Wellington, before undertaking a post-doctoral fellowship here at the University of Otago, Wellington campus. The main focus of my research has always been centred in developing better scoring tools for stratifying risk in cardiac disease. Identifying patients who are at increased risk of adverse clinical events means patient management can be personalised in order to improve patient outcomes.
My current research uses a mixture of molecular and genetic techniques in order to identify biomarkers relating to inflammation, small RNA molecules and genetic variants measured in patients who have suffered a heart attack. My research is done through Wellington Cardiovascular Research Group, and we work closely with cardiologists from Wellington Hospital in how we can best apply biomedical information so patients can benefit from better risk assessment models.
There are several postgraduate research opportunities (Honours, Masters, PhD) available in this field through the Wellington Cardiovascular Research Group.
