David Moody

David Moody

National Barley Breeder

David joined InterGrain in 2007 after a 25 year career in plant breeding and plant genetics with the Department of Primary Industries, and previously the University of Adelaide.  He has played an integral role in setting the governance and commercial platform for the business. Over the course of his career, he has become Australia’s most successful barley breeder, with over 50% of the national area sown to his varieties.  Whilst with InterGrain, David has released Australia’s highest yielding malting varieties, La Trobe, and more recently Spartacus CL and Maximus CL, new herbicide tolerant varieties.  His research interests remain in the areas of crop physiology and stress tolerance, and he is passionate about Australia’s opportunities as the malting barley producing epicenter for the Asian brewing markets.  David is actively involved in industry forums, currently being vice Chairman of the Grains Industry of Western Australia Barley Council.

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 ten wheat varieties (RockStar, 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 Calum Watt

Dr Calum Watt


Calum is the early generation national wheat breeder at InterGrain, joining the company in 2020. He holds a Ph.D. in barley quantitative genetics from Murdoch University in addition to a master’s degree in quantitative genetics and breeding from the University of Western Australia. His research focused on determining which genes control grain size in barley in a bid to better identify breeding targets to reduce screenings through a number of different approaches including genetic engineering (CRISPR-Cas9).

In his new role Dr Watt will focus on the development of hard wheats for Australia from the initial cross through to a nearly genetically fixed line with the aid of new breeding technologies such as genomic selection. Additionally, he will leverage new and existing partnerships with local and international researchers to incorporate new technologies and germplasm into the hard wheat program.

Dr Allan Rattey

Dr Allan Rattey

National Oat Breeder

Dr Allan Rattey is InterGrain’s national oat breeder.

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 plant 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.

Dr. Jayfred Godoy

Dr. Jayfred Godoy

National Early Generation Wheat Breeder

As InterGrain’s early generation wheat breeder, Jayfred is primarily involved in the genetic improvement and germplasm enhancement of udon and soft wheats. He is responsible for the creation of (targeted) breeding populations until achievement of pure-breeding genotypes, following several rounds of evaluation and selection. He is very keen to partner with pre-breeders and researchers to identify new strategies and apply the latest tools to improve selection efficiency in both high yielding and marginal environments.

Dr Godoy leads the implementation of high-throughput phenotyping and genotyping in the wheat and barley breeding pipelines. He is actively participating in several collaborative projects with leading Australian research institutions to upscale InterGrain’s phenomics capabilities.

Before joining InterGrain in 2018, Jayfred was a Postdoctoral Researcher in winter wheat breeding at Washington State University (USA). His research projects included genomic prediction and association genetic studies on wheat grain quality, agronomic traits, and spectral reflectance indices. He also worked on the application of various high-throughput phenotyping platforms in wheat breeding. Jayfred holds a Bachelor of Science in Agriculture from Visayas State University (Philippines), MS in Agronomy from Kansas State University (USA) and PhD in Crop Science (Plant Breeding and Genetics) from Washington State University (USA).
