Dr Kok Siew Ng
Lecturer in Chemical Engineering

Quad North 052


Dr Kok Siew Ng is a Lecturer (Assistant Professor) in Chemical Engineering at Brunel University London and an NERC Fellow. He joined Brunel in March 2022 after the completion of his 4-year independent fellowship at University of Oxford. He is also currently the Co-Investigator and Coordinator of the Oxford Agile project (Sprint 2) – a university-wide initiative focusing on tackling various environmental challenges using an interdisciplinary approach, funded through the £10 million NERC Changing the Environment programme. The sprint project aims to develop strategies for determining the best regional combination of nutrient recovery and utilisation options for both economic viability and environmental benefits.

Prior to joining Brunel, Kok Siew was a UKRI/NERC Industrial Innovation (Rutherford) Research Fellow and Lecturer in Chemical Engineering at the Department of Engineering Science, University of Oxford, from 2018 to 2022. During his time in Oxford, he was a Principal Investigator of the SYNERGORS project 'A systems approach to synergistic utilisation of secondary organic streams' (£0.5 million), funded by NERC. The project aimed to explore novel approaches to addressing challenges in organic waste management and achieving circular economy.  He completed his MEng Chemical Engineering with Chemistry (First Class Honours) in 2008, and later gained his PhD in 2011 from the Centre for Process Integration (CPI), The University of Manchester. After completing his PhD, he joined Process Integration Limited (PIL) as a consultant and later took up a position as a Postdoctoral Research Fellow at the Centre for Environment and Sustainability (CES), University of Surrey. 

Kok Siew is a chemical engineer by training with >10 years of research and industrial consultancy experience in systems engineering, process integration, techno-economic analysis and environmental life cycle assessment (LCA). His research vision is to develop novel and sustainable solutions from a systems engineering perspective, to facilitate the transition of the chemical, energy and waste industries from a fossil-based, linear system to one that is fundamentally sustainable by using renewables as the mainstream resources and by fully embracing circular economy principles. He has contributed to more than 10 UK and international projects funded by NERC, Innovate UK, EU FP7, Royal Academy of Engineering and Newton Fund. His research is significant in terms of addressing global challenges in the 21st century, aligned with the UN SDG 7 and 12, the UK Industrial Strategy, and international ambitions to achieving circular economy and net-zero target.

Kok Siew has published more than 30 articles including journals, book chapters and magazine article, and have co-authored an advanced textbook “Biorefineries and Chemical Processes: Design, Integration and Sustainability Analysis”. His work related to decarbonisation of energy systems has been recognised by the IChemE Junior Moulton Medal award (best publication) in 2011. Furthermore, Kok Siew has been nominated for the University of Oxford Vice-Chancellor's Environmental Sustainability Staff Award in 2022 for his contribution in actively promoting environmental sustainability through his research vision, which develops sustainable solutions from a systems engineering perspective. He is an Editorial Board Member of Resources, Conservation & Recycling Advances (RCR Advances) journal and also a reviewer for French ANR and UKRI/EPSRC proposals.

Kok Siew is enthusiastic in establishing international collaboration with researchers from multidisciplinary background. He has been working closely with international academic and industrial organisations in the UK, Europe, China and South East Asia. He has organised and participated in a number of British Council/Newton Fund workshops in Malaysia, Mexico, Brazil, Kazakhstan and China, and attended the Royal Academy of Engineering Frontiers of Engineering for Development Symposium “From feeding people to nourishing people”. He has a long-term ambition in influencing resources and waste management practices in developing countries towards sustainable development. Kok Siew is the Founder and President of the Society of Circular, Regenerative and Sustainable Systems (CRES). The aims of CRES society (knowledge exchange) and SYNERGORS consortium (research) are to promote and strengthen cross-disciplinary and cross-sectoral collaboration between the UK and international organisations in systems thinking and circular economy. His ambition in international development together with the objectives of SYNERGORS and CRES are well aligned with the UK Industrial Strategy in enhancing resource efficiency and mitigating pollution and waste materials, while achieving a sustainable industrial growth and a more resilient economy at global level.
