Zeng Qinglei is currently an Associate Professor at Institute of Advanced Structure Technology, Beijing Institute of Technology. He earned his Bachelor's and Ph.D. degrees from the School of Aerospace Engineering, Tsinghua University, between 2008 and 2017. He conducted his postdoctoral research at Johns Hopkins University from 2017 to 2019. In November 2019, he joined Beijing Institute of Technology. He has also been an academic visitor at Nanyang Technological University, Singapore. 

His research focuses on the dynamic failure of advanced materials and structures, as well as data-driven analysis and design of multi-functional structures. Dr. Zeng has led several research projects, including National Natural Science Foundation general projects and youth projects. He was selected for the 8th Young Talent Support Program by the China Association for Science and Technology. He currently serves as the Vice Secretary-General of the Beijing Society of Mechanics.



l Dynamic Failure of Advanced Materials and Structures: Exploring multi-scale dynamic damage and failure mechanisms under impact and explosion loadings in various materials, including metals, ceramics, lattice materials, and biomimetic materials. Developing physics-informed constitutive models and numerical methods (e.g., phase-field fracture models and discrete element models) for effective prediction of dynamic failure processes under extreme loading.
l Data-Driven Analysis and Design of Multi-Functional Structures: Utilizing additive manufacturing to design materials with unique mechanical properties under dynamic loading. Combining gradient topology optimization and machine learning to design microstructures of metamaterials to achieve customized stress-strain curves, improved dynamic crack resistance, and anisotropic multi-functional performances.
