Dr Juan Pablo Zoffoli

Dr Juan Pablo Zoffoli

Universidad Católica de Chile

Juan Pablo teaches at the School of Agriculture and Forestry of Pontificia Universidad Católica de Chile in the areas of fruit physiology and postharvest technology. His focus research has been to understand critical physiological disorders that affects Chilean fruit export, such as hairline in table grapes, internal browning and mealiness in peaches, abnormal softening in kiwifruits and pitting in sweet cherries, together with early prediction of internal browning and bitter pit in apples, using non destructive equipment. His lab, in collaboration with projects associated with packaging company, developed modified atmosphere packaging for the sweet cherry, blueberry and kiwifruit industry. The ongoing postharvest program for sweet cherries has made it possible to extend the storage time of this species and maintain constant growth in distant export markets such as China. The optimization and alternatives to the use of SO2 in the control of decay and the study of the rachis browning in new cultivars are some of the projects that are currently being carried out.

Although Dr Daniels does research on the evaluation of newly bred raisin grape selections in the Crop Development Division at ARC Infruitec-Nietvoorbij that led to the first South African raisin grape cultivar, Sundowner, for commercial use. He has 15 years’ experience in table grapes and have published scientific and popular articles from his PhD work that investigated non-destructive technologies to determine external and internal quality of table grapes. This included developing prediction models for sugar determination on whole berries in the vineyard and several parameters on whole bunches in the packing shed. He also looked at classifying browning during different cold storage periods.
Dr Carolyn Howell

Dr Carolyn Howell


Carolyn Howell was appointed as a Grapevine Irrigation Researcher in Soil and Water Science, ARC Infruitec-Nietvoorbij in 2010. She has worked on two completed WRC projects with Philip Myburgh and Vink Lategan. These projects (i) investigated the use of diluted winery wastewater for vineyard irrigation, and (ii) combined effect of canopy management and irrigation on grapevine performance. Currently she is the project leader of a SATI project to develop guidelines for the judicious irrigation of table grapes according to grapevine water potential measurements. She is also the project leader of a WRC-Winetech-ARC project investigating the use of winery wastewater as a resource for irrigation of vineyards in different environments.

Liaan Janse Van Vuuren

Liaan Janse Van Vuuren


My passion for agriculture, especially Viticulture started at a very young age and escalated into a career when I completed my studies in Viticulture and Oenology at the Stellenbosch University in 2008. Building on an everlasting passion I completed my Masters in Horticulture with the main focus on sustainable use of inputs including the sustainable management of nutrients like nitrogen. I believe the future lies in ensuring that every input is optimised to the extent that it contributes to the sustainable production of high quality yield, both quantitative and qualitative. Through identifying, quantifying an minimising certain limiting factors, optimal yields become a reality season after season.
