Research Fellow


Thiranja Prasad Babarenda Gamage received a Bachelor of Biomedical Engineering with Honours from the Department of Engineering Science at the University of Auckland in 2008. In 2016, he completed a PhD at the Auckland Bioengineering Institute on Constitutive parameter identifiability and the design of experiments for applications in breast biomechanics under the supervision of Prof. Poul Nielsen and Prof. Martyn Nash.

Biomechanics for breast cancer imaging

Address clinical challenges involved in diagnosing and treating breast cancer by melding biomechanics, state-of-the-art image processing techniques, and population based statistical analysis. My work has led to the development of a clinical workflow that automatically builds personalised biomechanical models, and is now being trialled at Auckland City Hospital.

Skin modelling group

Create and validate frameworks for identifying the mechanical properties of the skin in-vivo using non-invasive methods. The models are complemented with novel instrumentation and imaging techniques currently being developed at the ABI to create rich experimental datasets from which the mechanical properties can be more easily identified using design of experiment techniques.

Lung modelling group

Develop novel real-time full-field stereoscopic imaging systems for tracking lung surface deformation during ventilation. The rich experimental data obatined from these imaging systems provides the information required for quantifying the stress-strain behaviour of alveoli during early maturity and senescence. 

Develop multi-scale computational models of the lung that use this novel experimental data to better understand the mechanisms behind decline in lung function with aging. These models will help guide the development of new diagnostic methods to distinguish age related changes from lung disease.
