Introduction
I am a plant scientist specialising in image-based phenomic analyses of crops. Considerable expertise has been developed in high-throughput image analysis using proprietary LemnaTec and Phenospex-based systems as well as PlantCV and OpenCV.
I am adept at data management with advanced skills in Excel, R and Python. I currently manage two plant phenomics facilities on behalf of Agriculture Victoria.

Background
Lentil (Lens culinaris Medik.) is a globally-significant agricultural crop used to feed millions of people. Lentils have been cultivated in the Australian states of Victoria and South Australia for several decades, but efforts are now being made to expand their cultivation into Western Australia and New South Wales. Plant architecture pl...
The Dunvegan housing estate in the north-eastern Melbourne suburb of Macleod was initially subdivided in the early 1920s when the city's suburban fringe expanded and followed the path of the railways. Yet half a century would pass and significant government intervention would be required before the Dunvegan Estate would be transformed from a bare p...
Soil salinity can impose substantial stress on plant growth and cause significant yield losses. Crop varieties tolerant to salinity stress are needed to sustain yields in saline soils. This requires effective genotyping and phenotyping of germplasm pools to identify novel genes and QTL conferring salt tolerance that can be utilised in crop breeding...
This article describes a dataset of high-resolution visible-spectrum images of safflower (Carthamus tinctorius L.) plants obtained from a LemnaTec Scanalyser automated phenomics platform along with the associated image analysis output and manually acquired biomass data. This series contains 1832 images of 200 diverse safflower genotypes, acquired a...
Soil salinity is a major abiotic stress in Australian lentil-producing areas. It is therefore imperative to identify genetic variation for salt tolerance in order to develop lentil varieties suitable for saline soils. Conventional screening methods include the manual assessment of stress symptoms, which can be very laborious, time-consuming, and er...
Perennial ryegrass (Lolium perenne L.) is a dominant species in temperate Australian pastures. Currently, nitrogenous fertilizers are used to support herbage production for pasture and fodder. Increasing the nitrogen use efficiency (NUE) of pasture grasses could decrease the amount of fertilizer application and reduce nitrogen (N) leaching into the...
Background:
Numerous scaffold-level sequences for wheat are now being released and, in this context, we report on a strategy for improving the overall assembly to a level comparable to that of the human genome.
Results:
Using chromosome 7A of wheat as a model, sequence-finished megabase-scale sections of this chromosome were established by combi...

C4 grasses are favoured as forage crops in warm, humid climates. The use of C4 grasses in pastures is expected to increase because the tropical belt is widening due to global climate change. While the forage quality of Paspalum dilatatum (dallisgrass) is higher than that of other C4 forage grass species, digestibility of warm-season grasses is, in...
The population diversity of Doranthes excelsa Corrêa (Doryanthaceae) was measured from nine distinct geographic populations across eastern Australia, using random amplified polymorphic DNA (RAPD) markers. An UPGMA dendrogram of individuals was derived from squared Euclidian distances based on the Dice (1945) algorithm.
Three clusters corresponding...
The physiological effects of three auxins [indole-3-butyric acid (IBA), α-naphthaleneacetic acid (NAA) and 2,4-dichlorophenoxyacetic acid (2,4-d)] and two cytokinins [thidiazuron (TDZ) and N6-benzylaminopurine (NAA)] on in vitro morphogenesis of Doryanthes excelsa were measured. Longitudinal bud sections derived from immature inflorescences were us...
