Dr. Liew is an Associate Professor in Malaysia-Japan International Institute of Technology (MJIIT), Universiti Teknologi Malaysia (UTM) Kuala Lumpur. He has qualified himself as the Professional Engineer by Board of Engineers Malaysia (BEM) and Chartered Engineer under Engineering Council (UK), as well as Professional Technologist by Malaysia Board of Techologist. He is chartered member of Institution of Chemical Engineers (IChemE), and certified energy manager (CEM) under ASEAN Energy Manager Accreditation Scheme (AEMAS).
He specialises in Process Systems Engineering with emphasis on industrial energy and resources conservation using systematic algebraic process integration techniques, which fall in the scope of Urban-Industrial Symbiosis. He is now also actively working on renewable energy and hydrogen supply chain research through life cycle assessment, system optimisation and engineering education.
He is actively teaching in chemical engineering subjects. Beside technical knowledge, Dr Liew believe that softskills development is essential for undergraduate chemical engineering students. He is also actively involve in the use of active learning and project-based learning. He believes that students requires more soft-skills development aligned with their technical knowledge and ability development. To enhance the learning experience, he believe students could learn by doing, which project-based learning would very helpes the students to explore the new knowledge.
