Cell-matrix adhesion is the interface to sense and to translate extracellular mechanobiological signals into various cellular events. In particular, mechano-sensitive integrin-mediated adhesions on the plasma membrane are the signalling hub and orchestrate cytoskeletal reorganizations, tissue regenerations, and stem cell differentiations. While extracellular ligands bind and trigger the activation of integrin receptors, activated integrin heterodimers can dynamically assemble into completely different adhesion structures with distinct functions, including focal adhesion, reticular adhesion, hemidesmosome, podosome, and invadopodium. Thus, it is particularly important to broaden our understanding of adhesion regulations in the context of fundamental cell biology, as well as disease-related circumstances, such as cancer metastasis and atherosclerosis.

My research team aim to reveal the molecular basis of integrin-mediated adhesion, cell motility, and beyond. While cell adhesion is one of the most fundamental processes in cell biology, many grand challenges remain unsolved. Currently, we focus on the functional impact of spatiotemporal regulation factors, including phosphatidylinositol lipid biogenesis, small GTPase activation, and membrane curvature modulation, on the adhesion transformation, receptor trafficking, and invasive cell migration. With the cutting-edge tools of fluorescence microscopy and gene editing, my team will seek new opportunities to implement scientific discoveries into impactful biomedical applications.
