Prof. Holger Robert Maier received a B.S. in Civil Engineering (First Class Honours) and a Ph.D. in Environmental/Water Resources Engineering from the University of Adelaide in 1990 and 1996, respectively. Currently, he is a professor at the School of Architecture and Civil Engineering, University of Adelaide. His interests are in developing and applying methods that result in sustainable outcomes, especially when dealing with complex systems in an uncertain environment. Examples of this include the development of decision support systems for long-term disaster risk reduction under a range of plausible futures, the development of innovative bottom-up climate impact assessment methods, the development of adaptive approaches to urban stormwater management using smart technologies, and the development of approaches supporting the decarbonisation of the gas industry. Holger is the recipient of Biennial Medals from the International Environmental Modelling and Simulation Society and the Modelling and Simulation Society of Australia and New Zealand and is an International Advisory Board Member of Environmental Modelling and Software.
