Our Breeders

David Moody

David Moody

National Barley Breeder

Prior to joining InterGrain, David worked for the Department of Primary Industries in Victoria both as a barley breeder (1992 – 2006) and a cereal research scientist (2008 – 2010) based at Horsham. David also spent a period of time (2006 – 2008) working as a research manager with the Birchip Cropping Group.

David’s most previous role was in the management of the DPI cereal genetics group at Horsham where his main research interests were the genetics of physiological traits influencing barley’s adaptation to stress environments. His other responsibilities included the studies on the genetics and utilisation of primary synthetic wheats in wheat germplasm improvement and the evaluation of transgenic wheats for drought tolerance. David has a B. Ag. Sc (Hons) degree from the University of Adelaide.

Dr Hannah Robinson

Dr Hannah Robinson

National Early Generation Barley Breeder

Hannah is the early-generation barley breeder at InterGrain, having joined the company upon the completion of her research in 2017. Hannah holds a PhD in barley genetics from the University of Queensland, as well as an Honours degree in Plant Science from the Australian National University in collaboration with CSIRO. Her research focused on improved understanding of the genetics controlling the barley root system, as well as the potential role of roots in improved yield stability under water-limited conditions.

In her role at InterGrain, Hannah focuses predominately on the early stages of variety development, from crossing through to the generation of almost genetically fixed lines. In addition, she engages with researchers throughout Australia and across the globe to incorporate new technology and up-to-date research into InterGrain’s barley breeding program.

Dr Daniel Mullan

Dr Daniel Mullan

National Wheat Breeder

Dan is InterGrain’s Senior wheat breeder. Having joined the team in 2010, he has contributed to the release of nine wheat varieties (Devil, Vixen, Kinsei, Sheriff CL Plus, Ninja, Chief CL Plus, Zen, Supreme and Impress CL Plus). He specialises in developing yield stability in marginal environments, udon noodle quality and market development, cereal chemistry and new wheat product opportunities.

He leads the development of varieties with superior yield potential and stability for Australia and a global leading udon noodle breeding program. Emphasis is placed on developing and maintaining durable resistance to yellow leaf spot, septoria and the three rusts and improvements in functional end-product quality. To achieve this combination of targets the program has integrated a quantum leap in the availability of molecular marker technologies and selection approaches through its research linkages, along with the latest in physiological approaches and agronomic assessment. He maintains a position at the University of Western Australia and as an editor of Agronomy journal.

Dr Mullan is responsible for joint oversight of the company’s wheat pre-breeding, phenomics and marker research collaborations, pathology research and development and germplasm introductions and evaluation. Dan continues to develop a close working relationship with technicians, researchers, breeders and management groups across Australia and the global plant breeding community.

Prior to joining InterGrain, Dan worked at the International Maize and Wheat Improvement Center (CIMMYT), based in Mexico. During his time (2008 – 2010) at the institute he focused on wheat physiology and was the lead investigator in a GCP funded project targeting the genetic dissection of drought and heat adaptive mechanisms in bread and durum wheat. Previous to this, he completed a post-doctoral fellowship at CSIRO, Canberra, where he was the durum pre-breeder (2006 – 2008). In his role, he focused on the integration of drought tolerance traits into locally adapted germplasm. Dan has a Bachelor of Agricultural Science (1st class Hons) and a PhD in molecular genetics and plant breeding from the University of Western Australia.

Dr Allan Rattey

Dr Allan Rattey

National Early Generation Wheat Breeder

Dr Allan Rattey is the national early generation wheat breeder at InterGrain.

Before joining the company in 2018, Allan worked with Dow AgroSciences as the lead wheat breeder in Australia, where he oversaw the company’s national plant breeding structure and science. He was also accountable for Dow’s Southern Breeding Node – The Australian wheat breeding program.

As a wheat breeder Allan has actively pursued his keen interest in leveraging technology applied in global crops, including corn and soybeans, and successfully implemented several synergistic strategies within Australian wheat breeding. Allan has also contributed significantly to local research, particularly with his involvement in sponsored genomic research at AVR.

Prior to joining Dow, Allan worked with CSIRO as the national gateway breeder and trait pre-breeder, and has also spent time at BSES as a sugarcane breeder in Northern Queensland. Allan holds a Bachelor of Science, and a PhD in Quantitative Genetics from the University of Queensland.
