Cheng-Hsiang (Sean) Shei is a Research Assistant at the National Taiwan University (NTU) E3 Research Center. With an interdisciplinary background spanning energy engineering, environmental policy, and economic modeling, he focuses on research and applied analysis related to Taiwan’s energy transition and climate policy. His work centers on the intersection of policy, technology, and society, examining how evolving energy systems and regulatory frameworks shape socio-economic outcomes. His research interests include economic modeling, carbon pricing mechanisms, life cycle assessment (LCA), and electricity markets, with a particular emphasis on applying quantitative methods to generate policy-relevant, data-driven insights for sustainability transitions.
Sean received his Bachelor’s degree in Environmental Engineering from National Cheng Kung University. During his undergraduate studies, he participated in research on the life cycle assessment of electric motorcycles, with results published in a Q1 international environmental journal. He later obtained his Master’s degree from the Computer-Aided Engineering (CAE) division of the Department of Civil Engineering at National Taiwan University. His graduate research examined the distributional impacts of carbon pricing policies on households, with findings published in a leading international journal in ecological economics. Prior to joining the E3 Center, he worked as a climate and energy researcher at a non-governmental organization, where he analyzed emerging climate and energy issues and served as a bridge between academia and the media. His work included research and stakeholder engagement on solar photovoltaic deployment and related social acceptance debates, providing him with practical experience in policy communication and field-level stakeholder analysis.
In his current role at the E3 Center, Sean collaborates across multiple interdisciplinary projects spanning energy, economic, and environmental research. His work includes economic analysis of energy storage systems, industry–academia collaboration projects on energy and transportation systems, and international research on global SDG partnership networks. Through these projects, he contributes to integrating engineering analysis, economic modeling, and environmental assessment to support research that informs both policy development and societal decision-making. His work emphasizes connecting academic research with broader social contexts, ensuring that insights from energy and climate studies can meaningfully engage with public discourse and societal challenges.
