Professor in the School of Civil & Environmental Engineering
My research encompasses the fate of trace organic contaminants during conventional and advanced water treatment processes, with a particular emphasis on water recycling applications. Key areas of research include:
- Trace chemical contaminants in water
- Analytical methods (chromatography-mass spectrometry, etc.)
- Conventional and advanced water treatment processes
- Risk assessment and management
- Water quality impacts of extreme weather events
- Water reclamation and reuse
- Water treatment process performance validation and reliability assessment
- Probabilistic modelling
- Fugacity modelling
- Chiral environmental contaminants
- Indirect and direct potable water reuse (water recycling)
Interested research project students
Potential candidates are invited to register their interest in undertaking a research project (Honours, Masters, PhD or other) under the supervision of Professor Stuart Khan at the University of New South Wales (UNSW), Australia:
When suitable opportunities arise, I will contact suitable candidates who have previously registered their interest and encourage them to apply. Please note that this not an official UNSW form and its completion is not a formal application for enrollment at UNSW.
Interest in engineering
Why did you get into engineering?
I moved into engineering from a background in science. I did so because I felt the need to really apply technical knowledge and creative ideas in a way that could bring immediate practical benefits to human societies.
What are your research goals?
My overarching research goal is to facilitate the improvement of sustainable urban water management. I do this by improving our understanding of water treatment capabilities, water quality monitoring and risk management. These areas are crucial to support the increased application of more sustainable water supply options such as potable water recycling.
What do people not understand about what you do?
The technical ability to provide extremely high quality safe drinking water from recycled municipal wastewater (sewage) is poorly appreciated by much of the community. Similarly, the potential considerable advantages of some approaches to potable water recycling are commonly not clearly acknowledged. Society has much to gain from an improved understanding of capabilities of engineered urban water supply systems.
Advice for prospective environmental engineers
Environmental engineering requires sound knowledge and understanding of fundamental principles, but also an aptitude for creative thinking. Our challenge is to envision how the world could be and then to identify the practical means of achieving an optimum future for society.
