Our People

The Defence Technology Agency (DTA) is a small unit of the New Zealand Defence Force (NZDF) that has about 72 scientists, technologists, technicians and business services staff. We are all civilians and come from a variety of backgrounds.

Our scientists are specialists in their own fields and include chemists, physicists, metallurgists, engineers, operations analysts, psychologists, human systems specialists and environmental scientists. Organised into research groups, they also collaborate across workstreams to make sure a multi-dimensional approach is taken for all research tasks.

Read about our structure and governance.

We have a Director, a Principal Scientist and five Group Directors:


Dr Brian Young


Dr Brian Young started as Director of the Defence Technology Agency (DTA)  in 2012, after over 2 years as Director for Research at the University of Otago.

Previously, he served for 4 years at the New Zealand Embassy in Washington DC as the Ministry of Research, Science and Technology’s first Science & Technology Counsellor to the United States. 

Earlier, as a neuroscience researcher, he was a senior scientist at HortResearch, a Foundation for Research, Science and Technology Research Fellow at the University of Otago and undertook a period of post-doctoral work that was divided across the University of North Carolina at Chapel Hill, and the State University of New York at Stony Brook. 

He received a BSc(Hons) in psychology from the University of Canterbury (NZ) and a PhD in psychology (behavioural neuroscience) from Dartmouth College (USA).

Dr John Kay, MNZM

Principal Scientist

Dr John Kay worked initially in the undersea warfare domain. This included managing the Ocean Engineering section and leading various projects such as the design and development of a sea-floor acoustic measurement system.

From 2002 to 2010, John was the scientific advisor to the RNZN for a multilateral agreement on Surface Warfare Technology, and set up and chaired an associated specialist working group on infrared, visual and radar frequency propagation in the maritime environment.

In 2012 John started setting up, managing and growing the NZDF interests in research and development capabilities related to the utilisation and exploitation of space.

John’s career has been founded on active international engagement and collaboration. Within The Technical Cooperation Program (TTCP), John has been the National Leader in a number of maritime areas and the National Representative for Radar Technology and Sensor Systems until 2013.

John has a BE(Hons) electrical and PhD in Engineering from the University of Auckland.
