Singapore
• Executed multiple energy system modelling projects through collaboration with sectoral agencies and research institutions. • Organized and coordinated energy study-related events to foster communication and collaboration among various research communities. • Recruited and mentored student interns.
• Collaborated effectively with multiple Singapore government agencies, such as the Ministry of Trade and Industry and Energy Market Authority, to formulate the technical database structure for the reference energy supply chain, which consists of thousands of commodities and technologies throughout all energy supply and demand sectors. • Led the development of a large-scale energy system model to simulate and optimize Singapore’s reference energy supply chain given different energy policy requirements from government agencies, such as the Ministry of Trade and Industry and the National Climate Change Secretariat. • Conducted sensitivity analyses on key energy model parameters (e.g., renewable energy prices, carbon taxes, and market penetration rate) to investigate cost-effective decarbonization and net-zero emission solutions under different climate change targets. The results were directly reported to Singapore’s sectoral agencies to support policy-making. • Led a group of student interns to identify key barriers to implementing decarbonization policies in the Singapore context, and to study how other countries’ successful decarbonization pathways can be adopted in Singapore. • Conducted training courses on the energy model development and application to government sectoral agencies.
• Developed measurable system resilience concepts and exploited how to apply them in the design and evaluation of large-scale and irreversible investments in the highly interconnected supply chain of waste-to-energy systems. • Applied stochastic programming and robust optimization to develop quantitative model-based evaluation and optimization methods for designing resilient waste-to-energy system supply chains under unexpected disruptions. • Adopted game-theoretical and agent-based modeling approaches to model interactive behaviors of self-interested private operators, and analyzed effective policy interventions to sustain waste-to-energy system operation under different market competition environments.
• Analyzed the technical structure of the waste-to-energy supply chain in Singapore, and developed a life-cycle assessment approach for comprehensively evaluating the economic, environmental, and social performance of each system component within the supply chain. • Combined life-cycle assessment, chance-constrained programming, and stochastic programming approaches to develop optimization models for nested sustainable waste-to-energy supply network design under uncertain waste supply from municipalities.
• Developed mission-oriented system models for coupled problems in mega-city sustainability, focusing on unraveling and understanding the complexity of coupled systems as well as test-bedding based on calibration and evaluation of data, with the aim to build capability to extrapolate to other cities.
• Assisted in non-teaching matters and events.
• Assisted the general manager in implementing the printing equipment relocation project (worth US$1,200,000). • Designed parts of the newspaper logistics system layout inside the printing factory.
