Rachelle Ward

Research interests

  • Understanding drivers of slow digestibility of rice
  • Investigating the impact of environment on rice grain quality
  • Understanding the role proteins play in grain quality
  • Exploring quinoa as an emerging industry

Background

Dr Rachelle Ward joined NSW DPI as a Technical Officer in 2001 and since 2008 has acted as the rice cereal chemist after graduating from USyd in 2008.

Her PhD was conducted at NSW DPI, the University of Sydney and IRRI and focused on the stability of amylose content and structure when rice is exposed to elevated temperature and carbon dioxide levels during the grain-filling period.

As a cereal chemist, Rachelle contributes to the Australian Rice Partnership and a range of associated ancillary projects. She strives to improve the scope and understanding of grain quality analyses that reflect consumer and industry needs.

Rachelle has a particular interest in the impact of abiotic stress on grain quality, contribution of proteins to grain-cracking and texture and understanding the phenotype that results in slower digestibility.

More recently Rachelle has been exploring the potential of quinoa as an emerging crop in eastern Australia.

Rachelle enjoys engaging with a range of university and industry partners to ensure research outcomes remain relevant to the Australian Rice Partnership goals.

*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.
