Suzy Rogiers

Research interests

  • Grapevine physiology
  • Drought tolerance and heat stress
  • Plant water relations
  • Vascular transport
  • Fruit development


Suzy Rogiers joined the viticulture unit of the NSW Department of Agriculture* in 1997.

Suzy Rogiers is a principal research scientist with the NSW Department of Primary Industries and she is located at the National Wine and Grape Industry Centre in Wagga Wagga. She has researched fruit development and plant water relations for the last 15 years.

She completed her PhD on the physiology and biochemistry of Amelanchier alnifolia (saskatoon) berry ripening through the University of Alberta, Canada. Subsequently she joined the Department to study viticulture and she has a particular interest in plant responses to abiotic stresses.

Suzy has published on topics such as cell senescence, Shiraz berry shrivel, fruit split, source-sink relations on fruit-set, water-use efficiency, night-time transpiration and root-zone temperature effects on grapevine physiology and berry development. Her work relies on a combination of field based and controlled environment studies and she uses a whole vine approach.

Currently she is involved in an ARC Industry Transformation Training Centre project in conjunction with the University of Adelaide exploring viticultural methods to reduce alcohol levels in wine.

*NSW Department of Primary Industries was formed on July 1, 2004 through an amalgamation of NSW Agriculture, NSW Fisheries, State Forests of NSW and the NSW Department of Mineral Resources.
