Dr Hanwen Wu is a Principal Research Scientist in the Weed Research Unit of NSW Department of Primary Industries, based on Wagga Wagga Agricultural Institute. He lectured Weed Science and Farming System Research at Fujian Agricultural and Forestry University between September 1987 and October 1994. After the completion of his Master study at Wageningen University (The Netherlands) in 1996, he spent 6 months at Texas Tech University as a visiting scholar studying crop allelopathy. In 1999 Dr Wu received his PhD degree in Agriculture (Allelopathy) from Charles Sturt University (CSU).

He then worked as a Postdoctoral Fellow on genetic markers of wheat allelopathy at CSU between 2000 and 2002 and as a Weed Research Agronomist on integrated weed management of summer weeds with Leslie Research Centre, Queensland Department of Primary Industries & Fisheries, between 2003 and 2005. Since January 2006, he has been with NSW Department of Primary Industries. He is now a team leader in weed research at Wagga Wagga Agricultural Institute. His current research covers a broad range of areas including weed biology, ecology, herbicide resistance, genetic diversity, weed genomics, DNA barcoding for weed identification, integrated weed management and agricultural extension. He has recently co-authored a comprehensive 68-page “Silverleaf nightshade best practice management manual”.

Dr Wu supervises a number of PhD students and overseas visiting scholars in weed research and allelopathy. He is an Executive Board member of the NSW Weeds Society and currently sits on the editorial boards of “Allelopathy Journal” and “Journal of Cotton Research”.
