Luo Jixun

Research interests

  • Develop low glycemic index (GI) rice
  • Improve rice quality of cooking and texture
  • Develop new markers and methods to assist selection in Quality Evaluation Program (QEP)
  • Understand the functional domains in starch biosynthetic enzymes by protein 3D modelling

Background

Jixun’s PhD research, based at CSIRO Canberra, focused on starch biosynthetic enzymes functions, interactions, and their impact on starch structure and properties in cereal grains (barley, wheat and rice).

Jixun started his professional career as a Technical Officer at Tamworth Agricultural Institute of DPI NSW in 2015.

He was involved in the research on dough quality, in vitro digestion and textures of pasta made from durum wheat with novel glutenin sub-units.

Since 2016, Jixun is appointed as a rice chemist and primarily involved in the Australian Rice Partnership working on rice Quality Evaluation Program.
