    Biographical Statement

    He has organized several research projects relating to building a resource circulating society in Asia, sustainability assessment and indicator systems, environmental risk management, and ontology-based knowledge conceptualization for sustainability science. Recognizing the growing importance of Asia’s environmental impacts on the global environment, economics, and human society, his recent work focuses on developing sustainability assessment methods (multicriteria analysis) and developing future scenarios with policy measures to create and maintain sound interlinkage between ecosystem services, biomass use, and human well being in Asia.

    He has conducted on-site surveys in China (Shanghai), Vietnam (Ho Chi Minh City), and Malaysia (Sarawak) to investigate household energy and biomass resource use. He has also created future scenarios of these cities up to 2030 and estimated changes in energy consumption and CO2 emission for each scenario.

    Through his wide range background in ecological study, environmental systems research, environmental risk management, and sustainability science, he seeks to develop an integrated sustainable governance model based on environmental management and risk science for both human communities and ecosystems.
