My research vision is to develop systems thinking and circular economy approaches in resource management and develop best practices in response to the challenges arose during the transition from fossil to biorenewable economy.  I am enthusiastic in establishing national and international collaboration with researchers from multidisciplinary background. I have founded SYNERGORS consortium (Research) and CRES society (Knowledge Exchange) which aim at promoting and strengthening international, multidisciplinary collaboration between the UK and international organisations in adopting systems thinking approach in resource management.

I have published more than 20 peer-reviewed journals and book chapters, and have co-authored an advanced textbook “Biorefineries and Chemical Processes: Design, Integration and Sustainability Analysis”. My work in low carbon energy has been recognised by the IChemE Junior Moulton Medal award (best publication) in 2011.
