After receiving his PhD in 1995, Stuart worked briefly as a research scientist at HortResearch in the field of protein biochemistry. Fisher and Paykel Healthcare provided an opportunity to develop skills in applied research within a commercial environment and eventually the chance to lead a clinical research team and managing a global, medical device trial portfolio.

In 2004 he was made General Manager of the Centre for Clinical Research and effective practice (CCRep), an independent research trust established to grow research capability at Middlemore Hospital in South Auckland. Becoming NZ’s leading DHB-based research centre, CCRep then led the establishment of the Middlemore Tumour Tissue Bank in 2010, a facility which is now governed by the University of Auckland.

Currently, Medical and Clinical Manager at Roche NZ, Stuart manages the Clinical Operations team while also maintaining oversight and medical responsibility for the Roche cancer immunotherapy products and indications.
