麻豆传媒

I am a Lecturer in Mechanical Engineering at the School of Engineering, 麻豆传媒. I received my PhD in Civil Engineering from Sichuan University, where I was trained intensively in experimental characterisation and multi-scale modelling of geomaterials subjected to impact loading. I then conducted exciting research as a Postdoctoral Research Associate at the Impact Engineering Laboratory, University of Oxford in close collaboration with Rolls-Royce plc. There I designed and developed a novel impact-loading system for better understanding advanced aerospace materials and structures in extreme conditions.

I find myself always fascinated by the complex behaviours of a variety of materials and engineering structures. I use both experimental and computational approaches to establish and enhance our understanding. As an adventurous researcher, I have collaboration with international academics on topics ranging from impact and shock mechanics, additive manufacturing, micro-seismic monitoring, natural geohazards, stability analysis of underground structures, biomechanics etc.

Meanwhile, as a passionate educator, I help the younger generation of engineers read and analyse the mechanics of the surroundings through the language of mathematics and physics, explore unknown areas with learnt skills and enthusiasm, and develop the world with a warm heart and responsibility.

Previous experience

Research Associate, University of Oxford (2018 – 2023)

• Rolls-Royce and EPSRC Prosperity Partnership Grant\ Cornerstone: Mechanical Engineering Science to Enable Aero Propulsion Futures.
• Developed a split Hopkinson tension-torsion bar system for dynamic characterisation of aerospace materials at multiaxial stress states and elevated strain rates.
• Pressure, strain rate and loading path dependency of metals, polymers, composites: mechanical design and testing, microstructural characterization, and numerical modelling.

My research focuses on characterising, understanding, predicting, and improving the mechanical behaviour of materials in extreme environments. I am particularly interested in lightweight alloys, geomaterials, polymers, and little biomaterials.
