Research interests

The way we conduct our lives - as individuals and as a society - has a significant impact on the ecosystems on which we rely for our survival. Associate Professor Abbas El-Zein's research looks at how we can make rational decisions that take into account both our needs and those of the ecosystems that sustain us.

"Problems of environmental sustainability are challenging enough from a technical point of view, but they often require us to think about policy and politics as well.

"For example, one project I'm working on involves developing a better material for insulating contaminants buried in the soil, whether deliberately or not. When a site has been contaminated, we can identify the polluted area, dig a narrow trench around it and surround it with a material that's impermeable to the contaminant, ensuring that toxins do not travel beyond the contaminated site and that groundwater is protected. However, we can also take a step back and ask why this site was contaminated in the first place, where the toxins came from and what kind of policies can prevent this from happening in future.

"Another project involves working with local councils to assess the vulnerability of beaches to climate change. We know there's been a rise in sea level and that houses near the coast are affected. But it's not just about seawater rising and inundating the house - it's also about underground infrastructure such as pipes and cables being damaged, and whether the people who own or live in these houses have the means to undertake protective measures or need council assistance. Councils need to prioritise and focus their limited resources based on such assessments of vulnerability. These are some of the fascinating and complex interactions between the technological, economic and social dimensions of climate change.

"One thing I value about being a researcher at the University of Sydney is that I have a certain level of intellectual independence in terms of setting my own research interests, activities and priorities. There's a lot of value in that - it's wonderful - and not many workplaces afford you this privilege."
