Ir. Dr. Onn Chiu Chuen is an associate professor and researcher at the Department of Civil Engineering Faculty of Engineering, Universiti Malaya. He holds a BSc. in Engineering (Environment), MSc and PhD in Environmental Engineering from the Department of Civil Engineering, Universiti Malaya.  Dr Onn is a Professional Engineer registered with the Board of Engineers Malaysia (BEM) and a Chartered Engineer with the Engineering Council United Kingdom.

In line with his academic background, Onn’s research interest is quite wide-ranging under Environmental Engineering. However, his main interests are Life Cycle Assessment, eco profile and environmental (carbon, water, etc) footprints and impacts measurement, particularly within the context of products/building materials (waste incorporation), waste (WTE, biogas), energy (biofuels) and transportation (energy, modelling). Additionally, Onn is deeply involved in studying carbonation processes, which are crucial for carbon sequestration and reducing carbon footprints. His work in LCA extends to evaluating the entire lifecycle of products and processes, identifying opportunities to reduce environmental impacts and enhance sustainability.
