Professor Keith Hunter

Position : Former Professor, Department of Chemistry, University of Otago. Field : Trace metals in natural waters, chemical equilibria in marine and freshwater systems.

Professor Keith Hunter’s fascination with the ocean’s chemistry and his interest in studying this field is intertwined with his interest in how life first evolved in the oceans.

Practical science experiments at school and a group of friends who all cherished an interest for science were some of the reasons why Keith Hunter decided to pursue his passion for science by studying chemistry at the University of Auckland. He finished a master’s degree and was offered a scholarship to study in the UK. Keith had to decide on a field of study for his research and, after consulting with a colleague, decided to apply his knowledge in chemistry within environmental science, more specifically in marine chemistry. This area also aligned with Keith’s natural interest in and enjoyment of the ocean and marine environment.

After finishing his PhD at East Anglia University and a post-doctoral position in Paris, he got involved in a project called Geosecs – one of the first international research projects that looked at investigating ocean chemistry from a system science approach. Following this, Keith accepted a position at Otago University to help establish a new research direction in marine chemistry at the Centre for Chemical and Physical Oceanography. One of the innovative ideas Keith brought to the new department was the establishment of a ‘clean room’ lab that allowed more accurate measurements of metals in the ocean’s waters.

Clean labs

The moon landing had a great side-effect for science. When rocks were brought back from the moon, scientists decided they wanted to be able to study them in an environment where no terrestrial (Earth-based) contaminants could be found. As a result, clean labs were built that avoided all contamination. Other scientists started to use these clean labs for their own research. University of Otago Professor Keith Hunter experienced such labs when he was working in a clean lab in France. When he returned to New Zealand, he convinced the University of Otago that this was a good way to work, and a clean lab was built.

Keith points out that scientific questions don’t fall neatly into subject-specific areas, which is why it is so important to be working together across fields. He also believes that, as a scientist, you should be able to explain the relevance of your research to a 12 year old – if you can’t, it is probably not very important (or maybe you don’t understand it properly).

Fascinated by ocean chemistry

You would think that after many years researching, Professor Keith Hunter of Otago University would think he knows a lot. In fact, Keith finds the opposite is true – the more he learns, the more questions he has and the more that he still needs to find out. This natural curiosity drives him in his work. In addition, Keith enjoys his work with young researchers, guiding them as they first start out in their research studies.

From 2010, until his retirement in 2016, Keith was Pro-Vice-Chancellor, Sciences, at the University of Otago. In 1997 Keith was elected a Fellow of the Royal Society of New Zealand. He was awarded the Prime Minister’s Science Prize in 2011 and the Marsden Medal in 2014.

In October 2018 Professor Keith Hunter passed away. Read a tribute to him from the Otago Daily Times here.
