PhD, Plant Physiology
Suzy attained her PhD from the University of Alberta, Canada in 1997 where she studied the ripening physiology and biochemistry of saskatoon berries, a miniature pome fruit native to western Canada. Since then she has been investigating grapevine physiology with an emphasis on plant water relations and berry development. She is currently a Senior Research Scientist with the NSW Department of Primary Industries.
Specialisation: Berry development and vine water relations
Focus area: vascular transport, source-sink, water stress, stomatal conductance
Rising temperatures and severe heat events are a dominant concern in warm, non-irrigated regions as well as in irrigated regions experiencing reduced water allocations and high running costs related to irrigation. We are studying the implications of these factors on vine growth and water-use efficiency in several drought-tolerant and drought-sensitive varieties. Berry development is also responsive to the environment and the implications of high VPD and warm, dry soils on berry composition and size are under investigation.
