Paul’s lab studies how forces applied to the cell or the stiffness of the extracellular matrix affects cell structure and function. He an his group produce soft biocompatible materials to study how matrix stiffness alters cell structure, differentiation, and growth. In related work, Paul’s lab measures the structure and mechanics of cytoskeletal and extracellular matrix polymers using imaging, scattering, and rheologic methods, and examines how changes in cell membrane structure mediated by inositol phospholipids lead to production of signals that remodel the cytoskeleton.
Our lab studies several aspects of cell mechanics. In one project, we produce soft materials, usually hydrogels, to which cell adhesion proteins are linked to study how the stiffness of surfaces alters cell structure, function, and growth. Endothelial cells, fibroblasts, neurons and astrocytes each show unique dependence on substrate stiffness, and we seek to understand how they sense and respond to this mechanical cue. In related work we measure the structure and mechanics of cytoskeletal polymers using a variety of imaging, scattering, and rheologic methods. Further studies examine how changes in cell membrane structure mediated by inositol phospholipids lead to production of signals that remodel the cytoskeleton.
