Research

Envisioning Eco, Smart, Climate-Resilient, and Sustainable cities, my research encompasses several key interconnected areas. I am deeply involved in next-generation water systems, including Integrated Water Resource Management and Water Cyber-Physical-Social Systems, to enhance the resilience of urban infrastructure. I am also eager to integrate Socio-Environmental Hydrology with Real-Time System Modeling and Control, and am particularly interested in understanding the dynamics of water in climatic emergencies. By employing Systems Thinking, coupled with Data-Driven Numerical Modeling using advanced statistics and data science, I strive to develop models that capture the complex interdependencies among the critical urban services—energy, water, transportation, and communication—especially under extreme conditions.

I tackle these researches through theoretical, conceptual, and numerical modelling. Through these works, I develop more practical recommendations for governmental and non-governmental agencies on how to improve operational efficiency, increase disaster-related safety, and promote more just and equity to society.
