Background

Graeme is a Professor in Crop Science at the Centre for Crop Science in the Queensland Alliance for Agriculture and Food Innovation (QAAFI), which is a research institute of The University of Queensland, Australia.

Graeme conducts research on the physiology and genetics of complex adaptive traits in field crops with a focus on water productivity in cereals. His research underpins the development of mathematical models of crop growth, development and yield that enable simulation of consequences of genetic and management manipulation of crops in specific target environments.

His research approach provides unique opportunities to:

· Aid crop management and design for enhanced production in water-limited environments

· Enhance the utility of molecular breeding for drought adaptation, and

· Identify avenues to cope with climate risks in field crop production.

He is a Fellow of the Australian Agriculture Institute and was awarded the Australian Medal for Agricultural Science in 2013 and Farrer Memorial Medal in 2012.

Research impacts

Prof. Hammer's research capabilities are focused on the major cereal crops: sorghum, maize and wheat. His expertise in crop ecophysiology and modelling enable Graeme to investigate traits and management systems that have the potential to deliver productivity gains in water-limited production environments. He collaborates closely with plant breeders, geneticists, molecular biologists and agronomists in a range of national and international research projects in both public and private sectors. He is a Chief Investigator in the ARC Centre of Excellence in Plant Success in Nature and Agriculture (www.plantsuccess.org) and leads the UQ link to the APSIM Initiative, which is responsible for the on-going development of the APSIM modelling software platform (www.apsim.info), which is now used world-wide.

His research has focussed on traits and management systems that influence resource capture and resource use efficiency, including tillering and canopy development, root system architecture, maturity, carbon and nitrogen partitioning, light use and transpiration efficiencies. The detailed understanding that transpires from such work can generate approaches to phenotyping that provide avenues for linking with advanced approaches to molecular breeding and crop improvement.
