Professor Deirdre Lemerle is an agricultural weed scientist who worked 25 years for DPI at Wagga Wagga NSW Australia. She led the Cropping Program of the Weeds Co-operative Research Centre for 10 years. Deirdre was the inaugural Director of the Graham Centre for Agricultural Innovation from 2005 until 2015, an alliance between Charles Sturt University and the Department of Primary Industries which aims to increase sustainable productivity for mixed farming systems. She was awarded the NSW Agriculture 'Outstanding Achievement' in 1996, the Council of Australian Weed Science Societies Medal for 'Excellence in Weed Science' in 1998, and the CSU Vice-Chancellors Award for Research Excellence to Allelopathy Research Group 2000. She was selected to: be an ABC New Inventors program grand finalist with the 'Stubble Star' invention in 2005; attend Australia 2020 Summit (Rural Industries and Rural Communities) in April 2008; be in "10 Sisters" exhibit screened in the Australian Pavilion at the World Expo, Shanghai in 2010 featuring her profile about R&D for food security and agricultural sustainability; and be part in the Governor General's Delegation to China 6-12 June 2010. Professor Lemerle has published over 150 scientific papers and supervises post-graduate students. She has serves on various advisory and editorial boards.
