We study experimental soft matter physics and focus on the mechanics of soft materials and complex fluids. The main experimental approach in our lab is to apply precise imaging and mechanical measurements to study material properties span a wide range of length scales and time scales.  Such studies reveal nonlinear phenomena that expand the current understanding in the mechanics of soft materials. The insights gained in the research will benefit the design of smart materials based on soft matter and complex fluids. Beyond the scope of basic physical principles, we are also looking into expanding our studies to diverse areas including materials science, biology, and mechanical engineering, and etc.

Our research group is located on the scenery HKUST campus by Clear Water Bay (香港清水灣)。 We are constantly looking into passionate students and postdocs to join our lab. Please check the opening information to look up the updated hiring information in our group.
