Biography

Prof. Walsh’s research career commenced in 1999 with his role as a weed agronomist in AHRI (Australian Herbicide Resistance Initiative) where initially he explored herbicide resistance in wild radish (Raphanus raphanistrum) and techniques for managing herbicide resistant weeds. A focus of this research was the evaluation and development of harvest weed seed control systems. This work contributed to the now widespread understanding and use of these systems in Australian and global grain production. In 2016 Prof. Walsh moved to the University of Sydney where in the role of director weed research he led the northern grains regions Innovation in Crop Weed Control project. Research activities in this and additional projects (Machine learning for Weed Recognition, Site-specific weed control in ginger cropping systems) identified the opportunities of weed recognition technologies and site-specific weed control capability. This has resulted in more recent research efforts being focused on the development of novel non-chemical weed control techniques for in-crop use.

As part of the Gulbali Institute at Charles Sturt University (CSU) Prof. Walsh is continuing to research and develop novel weed control technologies with a focus on progressing suitable approaches through to commercialization. These research activities are integrated within the broader cropping systems research activities at CSU as well as being connected nationally and internationally with similar efforts.
