Dr Wendy Timms has almost 30 years of professional experience, mainly in Australia and Canada, on water and waste issues in both agriculture and mining. She has experience across consulting engineering, government, research and education as a hydrogeologist and environmental engineer.

Wendy leads and contributes to research projects funded by the Australian Research Council and various partners, generating new knowledge and technologies and developing leading practices. Information on publications and current research is available on Google Scholar and ResearchGate.

From 2012 to 2018 Wendy was the Director of Postgraduate Coursework and Senior Lecturer at UNSW School of Mining Engineering and affiliated with Mining Education Australia, the Australian Centre for Sustainable Mining practices (ACSMP), the UNSW Connected Waters Initiative. Wendy was a founding CI in the National Centre for Groundwater Research and Training, focused on aquitard reserach from 2009-2015. Prior to this Wendy worked as a consulting Senior Project Engineer (2003-2011) and as a hydrogeologist based in Gunnedah (1996-1997). Wendy has worked in Saskatchewan Canada (2002-2003) on water and waste related to mining and agriculture. 

Wendy has also worked on projects in NSW, Queensland and Northern Territory, Canada and New Zealand, and inspected project sites around the world including South Africa, Namibia, Thailand, Vietnam, India, Korea, Singapore, Italy, Morroco, Poland, France, UK, USA and Chile.
