Research Interests
The aim of my research is to use biomechanics as a framework for investigating how we move and control our arms and hands. The foundation for my work is the development of biomechanical models that represent accurately the mechanical actions of the upper extremity muscles; this includes detailed, quantitative studies of muscle architecture and moment arms that elucidate the relationships between muscle structure, musculoskeletal geometry, and function. The current focus of my research is on surgical reconstruction of hand function following cervical spinal cord injury. This work integrates in vivo sarcomere length measurements obtained during surgery with theoretical computer simulations of surgical procedures and quantitative assessments of post-operative hand function. This interdisciplinary effort aims to characterize the link between surgical technique and post-operative function and to optimize hand function for individuals who are paralyzed.
