Cheng Ning LOONG

Postdoctoral fellow

Cheng Ning has been my postdoctoral fellow since September 2022. We have collaborated extensively on fundamental research in the mechanics of fractal structures, including the modal dynamics of fractal trees, the static stability of evolving inter-fractal beams and two-dimensional media, analytical modal solutions for lumped stiffness-mass systems, and the non-smooth seismic response of rocking structures. More recently, we have been developing AI-agentic workflows to automate structural engineering processes, such as structural modelling, finite-element analysis, and code-compliant design. He is also a recipient of both the RGC Postdoctoral Fellowship Scheme and the Hong Kong PhD Fellowship Scheme.
