My research group focuses on soft matter physics, biophysics, and fluid mechanics, with a particular emphasis on emergent flow phenomena in soft materials and biological systems and their microscopic structural and dynamical origins. Our work is motivated by fundamental questions in statistical and biological physics, as well as engineering challenges in the design and processing of soft and biomaterials. We employ a range of state-of-the-art imaging techniques—including high-speed photography, confocal microscopy, and digital holographic microscopy—to probe fluid flows across small spatial and fast temporal scales. By integrating concepts from transport phenomena, statistical and thermal physics, colloidal and interfacial science, rheology, and biochemical engineering, we aim to develop a quantitative understanding of the complex flow behaviors exhibited by soft matter and biomaterials under both equilibrium and non-equilibrium conditions.
