Yeo Lip Siang
Research Associate
Biography
Lip Siang earned his Master's in Engineering (by research) from Swinburne University of Technology Sarawak Campus, Malaysia, in August 2023. He also holds a Bachelor's in Mechanical Engineering from the same university, awarded in August 2020. His master's research focused on the circular economy, specifically waste lubricant re-refining and biorefinery pathways. He specializes in applying mathematical optimization to complex decision-making problems related to process integration pathways and supply chain network design.
Currently, Lip Siang is a Research Associate at the Energy Studies Institute (ESI) at the National University of Singapore (NUS), where he focuses on hydrogen economy strategy. Before joining ESI in February 2025, he was a Research Engineer at the NUS Environmental Research Institute (NERI). At NERI, he contributed to atmospheric simulation research for the urban environment of Singapore, a government project funded by the National Environment Agency (NEA).
