My research focuses on investigating the mechanisms that underlie heart failure and vascular disease particularly in the context of hypertension and diabetes. To this end, we have developed a number of novel tools to assess cardiovascular signaling pathways.
- FRET-based biosensors to measure kinase activity and localization in living cells
- custom antibodies to measure biochemical modifications of proteins
- a variety of animal models with enhanced or reduced susceptibility to cardiovascular pathology.
With this research, we hope to contribute new understanding to the molecular basis of cardiovascular signaling that will culminate in potential clinical therapies for heart disease and atherosclerosis.

- The role of CaMKII in vascular physiology and pathology

My Summer Research Scholarship in the Department of Physiology was the highlight of my time at the University of Otago as I learnt many new skills, including how to carry out scientific research in a controlled manner, collecting and analyzing scientific data in an orderly fashion, and most importantly, learning to read and think critically.
