Dr Huub Kerckhoffs

Senior Lecturer

School of Agriculture and Environment

I grew up at a farm on reclaimed land (5.5 m below sea level) in the Netherlands, where my family is involved in growing a range of arable, vegetable and flower crops both in- and outdoors.

I graduated with an MSc in crop physiology at Wageningen University in the Netherlands. My PhD was on plant physiological functions of photoreceptors in tomato at the same university (supervised by Dick Kendrick/Wim Vredenberg/Maarten Koornneef).

I have a great interest in how light and plant hormones are controlling growth and development (e.g. flowering) in plant model systems at molecular biological, genetic and crop physiological levels.
I have worked in various laboratories at universities/institutes in the Netherlands (Wageningen University with Paul Struik),  UK (Leicester University with Harry Smith/Garry Whitelam), USA (University of Georgia, Athens, GA with Lee Pratt/Marie-MIchelle Cordonnier), Japan (Frontier Research Program, RIKEN, Wako-shi with Akira Nagatani/Dick Kendrick/Yuji Kamiya) and Australia (University of Tasmania, Hobart with JIm Reid/Ian Murfet/John Ross/Jiim Weller; and NSW Agriculture, Yanco, NSW with Laurie Lewin/Mellissa Fitzgerald), before coming to Crop & Food Research in Hawke's Bay, which became Plant & Food Research, where my main focus was on vegetable production systems.

I have joined Massey University since early 2013 within the Agriculture & Horticulture Group of the Institute of Agriculture & Environment. I'm lecturing in Horticultural Production, and specialised in vegetable production.

I'm the paper coordinator of Production Horticulture (284.101), and I'm contributing to Horticultural Production Systems (284.201), Horticultural Crop Development & Yield (284.301), Molecules to Ecology (119.154), Decision Tools for Primary Industries (119.281), Integrative Studies (119.373) and Plant, Cell and Environment (120.217) and I'm involved in postgraduate papers: Vegetable Crop Science (284.701) and Fruit Science (284.702), and supervision of postgraduate students.

I like the outdoors and spend time on/off-track within Ruahine, Kaweka, Tararua and Urewera mountain ranges when possible, if not on a race- or mountainbike.

I have a strong background on how light and hormones are controlling growth and development in a wide range of plant model systems, like potato, tomato, pea, arabidopsis and rice. My PhD was on plant physiological functions of photoreceptors in tomato at Wageningen University (Netherlands). I have worked on various related molecular biological, genetic and crop physiological aspects in several countries since before coming to NZ to Crop & Food Research in Hawke’s Bay where I worked on mainly vegetable production systems. I have joined Massey University since early 2013.

Keywords

I am a senior research scientist with 15 years’ postdoctoral experience in universities and research institutions in various countries (Netherlands, UK, USA, Japan, Australia, New Zealand). My specialist areas of expertise are in crop biology - plant physiology, within a strong agricultural and horticultural context, and ranging from a solid fundamental to an applied/practical horticultural research focus, in both laboratory and field settings.

Since arrival in NZ (late 2003) with Crop & Food Research (Hastings), I have been also involved in on-farm cropping and sustainability programmes with solid farming community partnerships using innovative knowledge transfer strategies aiming to create positive change within a strong farming (vegetable/fruit production) systems context (and led several FRST programmes worth over 4M$ in that space).

Within the Sustainable Production Environment team at Crop & Food Research (Hastings) and Crop & Fruit Production Systems at Plant & Food Research (Havelock Nth), I have been involved in a wide range of projects and programmes. Significant research efforts focussed on rural-community based initiatives to improve and optimise land use (change) and new cropping strategies, some in anticipation of climate change (opportunities), using innovative tools and new protocols often developed through novel participatory research partnerships, where my ability to adapt, facilitate, and communicate science outcomes to support farming (incl Māori) communities has been successful. In this capacity, I have been involved in several fruit, vegetable and orchard production systems, with solid research experience and knowledge transfer strategies dealing with many crops, like potato, māori potato, kumara, maize, sweetcorn, tomato, onion, broccoli, apple, kiwifruit, tamarillo, feijoa, passion fruit, citrus, walnuts, forage crops, green-manure crops and recently some new/potential bio-energy producing crops.

Specific areas of expertise:                                 

Fruit and vegetable production systems; Photomorphogenesis (phytochromes, cryptochomes, other photoreceptors); (Molecular) Genetics; Flowering; Plant Hormones; Plant Model Systems (tomato, Arabidopsis, pea, rice); Crop improvement and biotechnology; Science and (Māori) communities (participatory research approaches); Capacity building and extension in agricultural and horticultural (vegetable) industries; Crop biology (agriculture /horticulture); Plant physiology; Crop physiology; Horticulture; Agronomy

Teaching

I have been involved in teaching of plant science topics at the Wageningen University (NL), University of Georgia (US) and University of Tasmania at undergraduate level, and have supervised many under/postgraduate students involved in BSc, Honours, MSc and PhD projects as well. I have also assisted in a Research Techniques course (based on GenStat) for post-academic researchers in the Netherlands, and have been a student advisor for the Agronomy program at the Wageningen University.

I'm a lecturer Horticultural Production within the Agriculture & Horticulture Group at the Institute of Agriculture & Environment (IAE) since arrival at Massey since early 2013
