He is an industrious and talented Irrigation Specialist contributing top-notch technical abilities and knowledge, coupled with project management skills. Having designed water irrigation and effluent solutions within a range of agricultural, industrial and mining workplaces, Tim has in-depth understanding of the requirements each industry has, along with the necessary experience and the knowledge to get the job done right.
Dr. Phil Clunies-Ross
Phil is an environmental scientist, specializing in water resources management and environmental reporting. He utilises the power of data and effective science communication to inform and inspire positive environmental stewardship. Phil is proficient in the development of digital environmental reporting products, and believes these tools can be effectively deployed to engage stakeholders and inform decision-making. Before forming his own company eiQ Ltd, Phil worked in various scientific and digital-development roles. Phil holds undergraduate level degrees in biomedical science and environmental science, as well as a PhD in water resources management.
Associates
Professor Matthew Leybourne
Matthew Leybourne is a Professor in Analytical and Isotopic Geochemistry at Queen’s University, Department of Geological Sciences and Geological Engineering (Canada). His research is focused on developing new analytical methods related to solution and laser ablation ICP-MS and low-level trace element determinations, the geochemistry of fluids associated with ore deposits (groundwater, marine water and hydrothermal systems), geochemical exploration, the petrogenesis of igneous rocks, and the timing of the onset of Plate Tectonics. Matt is also the Co-Director of the Queen’s Facility for Isotope Research (QFIR). Previously, Matt held roles at Laurentian University, GNS Science in New Zealand, and the University of Texas at Dallas.
