A large amount of my past and current research focuses on areas of significance along the value chain of grape and wine production in relation to: viticulture management and wine production effects on grape and wine quality; relationships between grape and wine sensory attributes, composition and quality; molecular drivers of sensory profiles; perception of wine and beer astringency and body; alternative grape varieties in Australia; Australian wine terroir, regionality and provenance; wine consumer marketing, cross-cultural differences, perception, preference, emotions, context and predicting consumer behaviour; wine and food interactions; flavour additives in wine; wine neophobia; new wine and food product development; rapid wine sensory methods and wine and food extracts in health, mucositis and colon cancer.
My group have also conducted sensory research on abalone, chocolate, cheese, tomato, muntries, chicken meat, eggs and beer.
I currently oversee a number of projects. In 2015 I was awarded funding from the South Australian River Murray Sustainability – Industry-led Research Sub-Program (IRSP) PIRSA 2015 as Principal Investigator (PI) in addition to funding from the Australian and Chinese wine and beverage industries to define a niche wine market opportunity in China, determine consumer extrinsic and intrinsic wine preferences, generate wine and packaging concept designs, conduct market evaluation of concepts plus undertake a feasibility review to ascertain the capacity of the Riverland wine region to make and determine production costs of such wines. I'm also PI on a 4.5 year Wine Australia funded project to examine contextual effects on Australian wine consumers' perceptions and preference and the wine attributes that drive both consumer emotions, liking and willingness to pay which completes in mid-2017. Multiple publications have arisen from this research which were the first to reveal wine product evoked consumer emotions; novel consumer segmentation bases; better consumer research method practices; influence of consumer research testing situations and novel rapid methods for wine flavour profiling using trained panellists and consumers. In 2017 my collaborators and I (at 20% in-kind) were awarded a Wine Australia 5 year project on understanding the drivers of terroir in the Barossa Valley. The outcomes of my previous research have already been capitalised on, adding value to operations through improvements to production systems in areas such of salt management and fruit processing.
Since 2007 I have authored over 50 peer-reviewed publications in grape, wine and consumer research. Total career citations of 540/551 (ISI/Scopus), average of 56 citations per year (2011-2016), h-index = 18, top 5 papers cited 232 times in total. Most publications appear in J. Agric. Food Chem. (IF = 2.857). Several 2016 articles appeared in Food Chem. (IF = 4.052) and a paper in 2015 appeared in Anal. Chem. (IF = 5.886). I publish in high ranking journals in my field and have a relative citation index (RCI) of greater than 18.5 over the past 5 years. Based on data for the 2015 ERA round my RCI figures are well above the accepted threshold for an ERA score of 5.
I try to maintain deep engagement with industry to form strong working relationships and understand industry challenges with the aim to conduct industry-relevant research. I have conducted sensory evaluation training consulting to the wine and coffee industries but also conducted gratis training. As a sensory scientist and professor in tertiary wine sensory evaluation training I have considerable formal wine sensory research skills but also wine tasting and quality judging experience through my role as an international wine judge including: international wine judge 2016 Hawke’s Bay, New Zealand A&P Bayleys Wine Show and Sydney International Wine Competitions 2015, 2016, 2017, 2018; Advanced Wine Assessment Course ASVO scholarship applicant selection judge 2016, 2017; Wine and Chocolate Matching Workshop for the Wine Guild SA, May 2015; associate judge Sydney Royal Wine Show, 2013, 2014; judge Adelaide Hot 100 2011; associate judge Rutherglen Wine Show, 2008; Adelaide Hills Regional Wine Show November 2006 and Inland Irrigated wine show, Swan Hill, 1999; Adelaide Winemakers and Brewers Club Show judge; Australian National Amateur Wine and Beer Show judge at Regency TAFE; wine judge and prize presenter International Federation of Organic Agricultural Movements, Adelaide Convention Centre 2005 and liaise with the Royal Adelaide Wine Show, Australian Inland Wine Show, and Rutherglen Wine show to annually supply associate judges and stewards since 2002; and assist the Wine and Viticulture Journal coordinate and provide sensory evaluation for varietal report tastings. This allows me to maintain my palate skills and also interact with industry which has resulted in research opportunities and industry funding.
Most recent invited speaker invitations include – 2016 guest lecturer Eastern Institute of Technology New Zealand 28 September; 2016 keynote speaker NZSVO Taste of Tannin Red Wine Workshop Hawke’s Bay New Zealand 29 September; 2014 speaker Australian Society of Viticulture and Oenology (ASVO) seminar Quest for Optimal Yield and Quality, Mildura, Victoria, July 24th and 25th; 2013 speaker Australian Wine Industry Technical Conference Sydney, July; 2012 speaker ASVO seminar Objective Measures of Grape and Wine Quality, Mildura, Vic, July 25th and 26th.
In 2016 the Emerald Literati Network awarded a Highly Commended Paper for the paper “A fine wine instrument - an alternative for segmenting the Australian wine market”. I was a past member of the editorial panel for the Australian and New Zealand Grape Grower and Winemaker industry journal 2008 - 2011. I frequently peer review manuscripts for numerous scientific journals including but not limited to; Am. J. Enol. and Vitic., Aust. J. Grape & Wine Research, J. Agric. Food Chem., Internat. J. of Food Sci. Tech., Food Qual. & Pref., Food Res. Internat, Internat. J. of Wine Res. and Food Chemistry.
I’ve maintained relationships with previous colleagues outside of wine and set up research examining the role of grape seed extracts, now expanded to probiotics, mistletoe, almonds and Ganoderma in inflammatory bowel disease. I have supervised some 40 higher degree research students and have realised a number of publications from these. Currently, I'm principal supervisor of 4 PhDs and 1 Masters student and co-supervise 3 other PhDs.
I have an international profile as an academic and industry collaborator having formed successful links with the Australian Wine Research Institute, University of South Australia; Department of Primary Industries Victoria; Örebro University, Sweden; University of California Davis; QiStatistics, UK; E&J Gallo (California); Treasury Wine Estates Pty Ltd; Pernod Ricard Australia; Tarac Technologies; Laffort Oenologie; Dr Herb Meiselman (Herb Meiselman Training, USA); Norwegian Institute of Public Health, Oslo; groups within the School of Agriculture, Food and Wine, CSIRO, SARDI and PIRSA, resulting in award and submission of grants, publications and student supervision.
