Dr. Lin-Hai Han is a tenured Professor of Structural Engineering at Tsinghua University. He established the life-cycle-based analytical theory and design methodology for concrete-filled steel tubular (CFST) structures. He is ranked among the top 4 scientists for Career-Long Impact in the field of Civil Engineering, according to the latest Stanford/Elsevier' s World' s Ranking of Top 2% Scientists.

He was elected a Fellow of IStructE, UK, and is entitled to use the title "Chartered Structural Engineer". He is also a Fellow of ASCE, US and ICE, UK. He is the founding Chair of the Subcommittee of Steel-Concrete Composite and Hybrid Structures (TC 71/SC 9), the International Organization for Standardization (ISO).

His academic work underpinned numerous infrastructure projects, including large-scale buildings, bridges, electric power towers, etc. He is the editor-in-chief of the National Standard of the People' s Republic of China GB/T 51446-2021, Technical standard for concrete-filled steel tubular hybrid structures. From February 2022 to November 2024, he served as the Convenor of ISO/TC 71/WG 2, leading the development of the international standard ISO 16521:2024, Design of concrete-filled steel tubular (CFST) hybrid structures, the first ever ISO standard on CFST structures. Subsequently, the UK, Denmark, the Netherlands and Belgium have adopted this standard as their respective national standard (BS ISO 16521:2024, DS/ISO 16521:2024, NEN-ISO 16521:2024 and NBN ISO 16521:2025, respectively). His proposed constitutive models of concrete, resistance calculation methods for structural members, etc., were systematically adopted by these standards.

As the leading researcher, he was awarded the State Natural Science Award (Second Prize) of China in 2019. He was the winner of the Prize for Scientific and Technological Innovation from the Ho Leung Ho Lee Foundation in 2023. He was the recipient of the ASCE Region 10 Distinguished Service Medal Award in 2024. He was awarded the ISO Excellence Award by ISO in 2025, becoming "the first awardee in the area of concrete materials and structures globally".
