Tim is Director of TREENET Inc., the national, non-profit research and education organisation dedicated to improving Australia's urban forests. He began volunteering with TREENET in 1997 and his passion for bringing macro and micro-nature back to cities and towns to improve human and environmental wellbeing continues to this day. Tim's experience 'on the tools' and in technical roles in the private and public sectors underpins his practical approach to applied interdisciplinary research. His research interests include climate-resilient urban forestry and integrated green engineering that supports trees and other vegetation so interactions between roots, built infrastructure, water and soil can deliver maximum benefit to communities and the broader environment. Current research projects include investigating the effects of stormwater harvesting on growth and transpiration rates in urban trees; the capacity of urban soils to retain stormwater; and the effects of stormwater infiltration on reactive soil. Tim serves on the Advisory Board and Management Committee of TREENET Inc. and is a member of the Institute of Public Works Engineering Australasia and Arboriculture Australia. He has served on the Significant Tree Committee of the National Trust of South Australia (2002-2012) and the Steering Committee of the South Australian Urban Forest Biodiversity Program (1997-2006).
