Simon Townsend is manager of the Aquatic Health Unit with the Department of Natural Resources, Environment, The Arts and Sport of the Northern Territory Government. He is also an honorary research fellow at Charles Darwin University. Simon has a wide range of interests in aquatic ecology and limnology of the wet-dry tropics that span rivers, floodplain lakes and reservoirs, with academic interests in algal ecology and water quality. He has been a resident of Darwin since 1983, with one brief year-long sojourn as a researcher with the Australian Antarctic Division of the Australian Government. His doctoral study with the then Northern Territory University examined the significance of wet-dry tropical climate on the limnology two adjacent reservoirs that differed in their physical characteristics. Simon is a member of the TRaCK team, and has led projects on river health and water quality monitoring and research into river algal ecology. He is keen to see river health monitoring is scientifically credible, communicated and informative for water resource management, and considered a societal activity rather than one only undertaken by a Government agency. Simon has co-authored more than 40 book chapters and scientific papers.
