Researcher Summary
Aisling O'Sullivan is a Professor of Ecological Engineering.
She leads CELTS, the Centre for EcoLogical Technical Solutions (www.celts.org.nz). Her research focuses on creating design solutions that are holistic, valorise waste resources and, align to the circular economy. Most of the research projects include Clean Water Technologies (CWT) and are conducted in partnership with councils, Iwi and industry.
Aisling's research topics include;
1. Water Quality Monitoring and Modelling:
(i) quantifying the amount of elusive metal and nutrient contaminants by collecting field data and employing environmental data sensors.
(ii) modelling contaminant loads using experimental data and modelling tools (e.g. our stormwater model MEDUSA).
(iii) modelling hydraulics in passive treatment systems to better understand their performance (including across regional climates).
2. Clean Water Treatment Technologies:
Designing wastewater treatment solutions that are holistically sustainable (e.g. ecologically, economically and culturally appropriate). Applications have been applied to the mining, galvanising, stormwater and agricultural sectors. New designs have included modified engineered wetlands, green roof technologies and storm water systems such as raingardens and her patented Storminator™ downpipe technology. All of these have used wastes as an active treatment media.
3. Life Cycle Assessment (LCA): quantifying whole-of-life environmental impact(s) of current and future wastewater treatment systems using LCA modelling software (Simapro), Ecological Footprint metrics and a Wellbeing Framework.
4. Engineering Education: pedagogy of engineering curricula to enhance engineering students’ competency in sustainab
