Dame Patsy and Sir David visited the Auckland Bioengineering Institute to find out more about the cutting-edge research being undertaken there.
The Institute applies engineering sciences and technical innovation to medicine and human physiology. The results of their work are already being rolled out commercially for use in labs and hospitals around the world.
Dame Patsy met researchers working on improvements in the delivery of drugs under the skin; investigating the role of abnormal electrical wave activity in digestive illnesses; and using computer modelling to better enable surgeons to make the best decisions in joint replacement surgery.
