Alain has conducted collaborative researches in the domain of grapevine physiological responses to abiotic factors (water, light and temperature) within integrated and multi disciplinary approaches from the vineyard to the wine.  These researches have been done in Australia, France and South Africa mainly. 

Alain was project leader and/or chief investigator in various funded project in France, South Africa and Australia.  These projects were mainly related to grapevine physiology and the effect of abiotic factors (water, light and temperature) on grapevine and fruit development and composition. Within integrated approaches from the vineyard to the wine, for most projects wine tasting and sensory analyses were performed with the contribution of expert colleagues.

At INRA Pech Rouge (2017), with two of my former PhD students:  Drs Hernan Ojeda (left) and Flor Etchebarne (middle)

Working on Cabernet Sauvignon ripening with Professor Zhenping Wang (Ningxia University, China, 2018)

Multidisciplinary and integrated R&D projects are needed to answer to wine industry complex questions

The few publications listed below give a flavour of the reserach results obtained through the funded projects and the PhD students main achievements.
