    Interested in a holistic approach to addressing complex environmental challenges, I focus on various aspects including water and wastewater treatment systems, the water-food-energy nexus, water quality analysis and modelling, hydrological modelling, the impact of climate change on water infrastructure, and health risk assessment and management in water/wastewater systems. My aim is to identify management targets for improving water supply systems and living conditions.
