School of Civil & Environmental Engineering
Biography
I am dedicated to ensuring that growing populations have access to sufficient and safe water. My research focuses on safeguarding water resources by addressing water pollution. Through my work, I develop knowledge and mathematical tools to understand the terrestrial processes that degrade water resources, crucial for creating effective pollution control measures.
I have expertise and experience in physically-based and statistical modeling techniques across various computing platforms. I combine local field data with information from global databases to unravel the mechanisms behind hydrological and pollution processes. I have been at the forefront of applying Bayesian Networks (BNs) in stormwater quality modeling. This pioneering work has since expanded to tackle broader water quality issues, including surface and groundwater pollution, water consumption, and health risks.
My long-term research aims to explore how environmental changes and urbanisation impact the degradation of water resources.
Expertise related to UN Sustainable Development Goals
In 2015, UN member states agreed to 17 global Sustainable Development Goals (SDGs) to end poverty, protect the planet and ensure prosperity for all. This person’s work contributes towards the following SDG(s):
