Biographical details

Associate Professor Abbas El-Zein has a BE in Civil Engineering from the American University of Beirut, Lebanon, an MS (with distinction) from the University of Southampton in the UK, an MS in Environmental Science from the ENPC in Paris, France and a PhD in Computational Mechanics from the University of Southampton. He worked in the UK for 3 years as a computational analyst advising automotive and aeronautical industries worldwide. He joined the University of Sydney in 2004.

Abbas is interested in problems of contamination and hydro-mechanical behaviour of saturated and partially-saturated soils, assessment of vulnerability to climate change, as well as the broad links between technology, poverty and environmental degradation in the developing world. He has supervised a number of Engineers without Borders honours thesis projects on water, sanitation and food security in Cambodia and Nepal.

Research interests

Anyone interested in addressing environmental problems in the 21st century needs to be prepared to cross disciplinary boundaries every now and then, says Associate Professor Abbas El-Zein. His own research, which focuses on environmental geomechanics and environmental risk, draws on the disciplines of computational mathematics, environmental science and engineering, among others.

"Environmental problems in the 21st century are complex and multifaceted.

"For example, if we want to understand how groundwater becomes contaminated, we need to consider how water moves in the subsurface, which involves hydrology and soil mechanics. We also need to look at how chemical substances become dissolved in soil water or filtered by soil grains, which takes us into soil physics, chemistry and thermodynamics.

"On the other hand, if we want to know how to prevent groundwater contamination, we might build an engineering system to prevent contaminants entering the groundwater, or we might find that a better solution is to come up with policies that prevent the use of those contaminants in the first place, or that ensure they don't pose a threat to the groundwater. This requires some understanding of the social, economic and legal context within which technology operates. Without such an understanding, the solutions we come up with might not be quite the right ones.

"Approaching problems in this cross-disciplinary way is part of the excitement. It's complex, of course - but, on the bright side, there's not a moment of boredom! It makes your mind richer, and it makes you humbler as you get a glimpse of the wonder and complexity of what others are doing."
