About关于我
My research centres on the mechanics and physics of material interfaces. I investigate how interfacial forces, deformation, and molecular transport interact to determine the behaviour of soft polymer networks and coatings. My approach integrates quantitative optical experiments with continuum mechanics and numerical simulation, connecting observations of local interfacial processes with the mechanical response of the material.
During my doctoral research at the Hong Kong University of Science and Technology (HKUST), I studied wetting, adhesion, and phase separation at soft polymer interfaces. Using in-situ optical imaging and mechanics-based models, I investigated the redistribution of free chains within polymer networks, the growth of wetting-induced phase separation, and droplet motion on surfaces with stiffness gradients. These studies examined the roles of surface stresses, poroelastic transport, and viscoelastic dissipation in soft-interface dynamics.
My master's research in experimental photomechanics established the foundation for this work. I developed expertise in non-contact optical measurements of interfacial deformation and failure, with particular attention to coating fracture toughness and the accuracy of microscale displacement measurements. My experimental background includes digital image correlation (DIC), shearography, confocal microscopy, and white-light interferometry, complemented by basic photolithography. Interfacial and fracture mechanics, together with finite-element analysis, underpin the interpretation and validation of these measurements.
I also use computational mechanics and multiphysics simulation to support experimental design, test mechanistic interpretations, and analyse engineering systems. This work includes nonlinear contact, cohesive-zone modelling, fluid–structure interaction, and moving-mesh flow simulation.
I received my Ph.D. in Nano Science and Technology from the Department of Physics at HKUST under the supervision of Prof. Qin Xu. I previously earned an M.S. in Mechanics from Jiangsu University and a B.S. in Civil Engineering from Qingdao University of Technology.
我的研究以材料界面的力学与物理机制为核心，关注界面作用力、材料变形与分子输运如何共同决定软聚合物网络及涂层的行为。通过结合定量光学实验、连续介质力学与数值仿真，我研究局部界面过程与材料整体力学响应之间的联系。
博士阶段，我在香港科技大学研究软聚合物界面的润湿、黏附与相分离。通过原位光学成像与力学建模，考察聚合物网络中自由链的再分布、润湿诱导相分离的生长，以及刚度梯度表面的液滴运动，分析表面应力、多孔弹性输运和黏弹性耗散在软界面动力学中的作用。
硕士阶段的光测实验力学研究为上述工作奠定了基础。我主要利用非接触式光学方法表征界面变形与失效，重点研究涂层断裂韧度及微尺度位移测量的准确性。实验技术涵盖数字图像相关（DIC）、剪切散斑干涉、激光共聚焦与白光干涉，并具备基础光刻经验；结合界面力学、断裂力学和有限元分析，对测量结果进行解释与验证。
此外，我运用计算力学与多物理场仿真开展实验设计、机理验证及工程系统分析，相关工作包括非线性接触、内聚区建模、流固耦合与动网格流动仿真。
我于香港科技大学物理系获得纳米科学与技术博士学位，师从许钦教授；此前于江苏大学获得力学硕士学位，于青岛理工大学获得土木工程学士学位。
