Professor Gillian Whalley started he career as a cardiac sonographer in 1985. She moved into a research role in 1990; her research interests include using echocardiography for prognosis; the role of echocardiography for screening in asymptomatic high-risk populations; and indexing heart size for body composition. Her PhD thesis (2006) evaluated the role of echocardiography in the management of patients with heart failure. Gillian has led several multi-centre international collaborative projects, sometimes combining data from thousands of patients to show the independent clinical value of echo measurements. Currently, she balances clinical sonography work with her academic role at the University of Otago in Dunedin, New Zealand.
