Research focuses on nature-based solutions like constructed wetlands for wastewater treatment in hot and arid climates, circular economy models for sewage sludge management, and green infrastructure development. Key projects include the world's largest industrial constructed wetland in Oman (175,000 m³/day) and Saudi Arabia's Red Sea Project system (16,000 m³/day).

Recent publications emphasize climate adaptation and sustainable resource recovery, with 2025 studies on sludge treatment reed beds, GCC circular economy transitions, and biochar applications in wastewater reuse. His work bridges ecological principles with engineering practices for global sustainability challenges.
