Dr David Hume is an AgResearch senior scientist and the recent winner of the Ballance Science and Research Award at the Beef+LambNZ Awards (October 2024). The award recognises excellence in science and research activities that are of direct relevance and benefit to the sheep and beef sector. David is an agronomist who specialises in endophyte research. He is based at our Grasslands Research Centre in Palmerston North. 

Scientist Profile

When David Hume, after having his arm twisted, reflects on his career as a researcher, all 41 years of it, recurring themes quickly become evident. 

He fully endorses the concept that science is a team sport, and this is only partly to do with modesty. 

David’s career has been defined and intertwined with the AR37 endophyte and as such he feels as if he has been labelled as chief promulgator of the research, one of AgResearch’s biggest success stories. 

The more accurate and prosaic version of the story, he says, is that many different researchers, with many different skills, combined their talents, ambition and funding with a healthy dose of luck, and with hard work achieved something close to the holy grail in research; an idea, a big stretchy idea, that ended up creating tangible and measurable impact. Billions of dollars of it.  

With success comes attention. Something that David understands and accepts. And given his links to AR37 (which we’ll cover in more detail shortly), his longevity and congenial personality, he’s frequently asked to talk about both. 

Ever the pragmatist he’s created a slide deck that help him neatly sums up 40 years of work in 15 minutes. The last slide (see below) is the second best. It lists three key lessons from his career. The first is, ‘Look for opportunities in all directions’.

And as you can see (above) a family of Meerkats, scanning the horizon, working as a team, is lesson No 1. 

The second is, ‘adapt fast and with care’ which David translates into shorthand. It means ‘don’t be a luddite’. 

The third is ride the funding wave, and this correlates to David’s own career-defining research on endophytes, a wave he’s still riding. 

David believes the lessons which were learned and relearned during his career, are as relevant today as they have ever been given the current science sector is being reviewed, funding is tight and opportunities seemingly scarce 

The bit that is missing, from the slides at least, is the how. The how do you adapt, how do you ride a funding wave, and how do you look for opportunities? 

For that we’ll need to delve a little deeper into David’s story and go back to where it all began. 

 

David enjoys getting his hands dirty in the field and staying connected and talking directly to farmers. "It's where our best ideas often come from".

 

David is a Cantabrian, and he was born and raised in a house beside a main Christchurch thoroughfare. In cities today, houses beside utilitarian infrastructure such as four-laned carriageways that link an airport to a CBD, are at best nondescript. However, Memorial Avenue was, and still is, home to some of the city’s most preeminent gardens.  

In spring they burst with colour. They are a rare confluence of green thumbed and house proud homeowners. David’s father was an ordered man and loved his garden. This instilled in his son an early love for the environment. After graduating high school, he enrolled at Lincoln College (now Lincoln University), and majored in agricultural science. He excelled and had his pick of a handful of jobs upon graduation. He chose the DSIR at Grasslands. Opportunities abounded including a sponsored a scholarship to become the first New Zealander to study for and be awarded a PhD from Wageningen University in the Netherlands. 

David and his wife Karen returned home from their three-year stint in the Netherlands with two children and put down roots in Palmerston North. During a short scholarship in Victoria, Australia, in the mid-1990s, he developed professional connections and worked on endophyte trials. 

Endophytes are fungi that live inside the tissues of many plants. They form a finely balanced interrelationship where the endophyte protects the plant from pests in return for nutrients and a safe home. 

Scientists had discovered they could transfer them from plants from different parts of the world and put them into productive NZ cultivars. And David, ever alert to an opportunity, used his agronomy skills to grow and test them in plots and paddocks.
