Deputy Director


Merryn Tawhai graduated from the University of Auckland with a PhD in Engineering Science in 2001. She leads a research programme at the Auckland Bioengineering Institute (ABI) in applied computational physiology of the respiratory system. Merryn is the Deputy Director of the ABI and Director of the Medical Technologies Centre of Research Excellence (MedTech CoRE). She was awarded the 2016 MacDiarmid Medal by the Royal Society of New Zealand (RSNZ) Te Apārangi, is a Fellow of the RSNZ, and a Fellow of IAMBE and AIMBE.  

Research | Current

My research is focused on the development of integrative computational models of the pulmonary system and their application in understanding structure-function interactions in normal physiology and in the pathophysiology of pulmonary disease. I have particular interest in the application of computational modelling to improving clinical diagnosis and monitoring of pulmonary disease, particularly in the older lung.
