Lecturer in Chemical Engineering

Quad North 052

Research area(s)

My research employs systems engineering approach (conceptual design, simulation and mathematical modelling and optimisation, process integration), techno-economic assessment, environmental life cycle assessment (LCA) and policy analysis in developing innovative strategies for sustainable industrial system design and resource management.

My research spans chemical engineering and environmental management, with particular focus on the following two areas:

  • Sustainable industrial system design
  • Sustainable resource and waste management

Research Interests

  • Biorefinery system design (biomass and waste valorisation; gasification; pyrolysis; hydrothermal liquefaction; Fischer-Tropsch; aviation fuel production)
  • Decarbonised polygeneration system design (carbon capture and utilisation; combined heat and power; fuel and chemical production)
  • Resource recovery from waste and Circular economy (management and valorisation of municipal solid waste including food waste, residual waste, recyclable waste)

My research involves multidisciplinary and international collaboration in view of promoting sustainability and circular economy practices in the developing countries and addressing global challenges. I am currently leading SYNERGORS consortium and CRES society. Our initiatives are featured in the SYNERGORS Final Report:
