Research Interests

Prof Burger is a specialist in membrane-based desalination and water treatment. His related research is application-driven, focusing on the practical aspects of membrane fouling, energy consumption and efficiency. He also supervises research in thermal separation technology, specifically focussing on topics such as distillation hydrodynamics and phase-equilibria, as well as the associated underlying chemical thermodynamics.
