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.
