Dr. Long's research interests focus on the nonlinear mechanics of soft materials and flexible structures, with applications in developing advanced materials and structures, and understanding biological materials. Dr. Long have worked on a diverse range of research projects in solid mechanics and biomechanics. These include fracture mechanics of soft elastomers, continuum mechanics modeling of light-activated or thermally-activated polymers, characterization of three-dimensional (3D) mechanical tractions of biological cells, adhesive contact mechanics of thin membranes, mechanics of bio-inspired fibrillar adhesives, and adhesion in biological systems. Currently Dr. Long's research group is studying the fracture mechanics of soft elastomers and gels, the contact mechanics involving soft materials, the mechanics of advanced composite materials, and mechanics of biological cells with applications in microfluidic devices.
