We focus on characterization and simulation of the musculoskeletal system. Broadly, this includes elucidating structure-function relationships in orthopaedic tissues and studying the role of these tissues in human movement. Specific research projects are highlighted below:
Structure-Function Mechanisms in Orthopaedic Soft Tissues
When skeletal muscle is stretched, how do the cells and extracellular matrix deform and transmit force? How does fluid flow in the tissue? We seek to answer these questions with material testing and image analysis techniques to better understand the basic science of skeletal muscle function.
Modeling Lower Limb Rotational Morphology
How does femoral anteversion, a rotation of the femur that causes “toe-in” gait, affect whole body biomechanics? How could femoral anteversion lead to tissue degeneration and impairment, and how can we prevent this degeneration? This work is being conducted in collaboration with Dr. Mark Seeley at Geisinger Health Systems.
Bighorn Sheep Horn and Skull Impact Analysis
How do bighorn sheep horns and skull help dissipate energy during ramming and reduce brain cavity accelerations? By developing an understanding of how the horn structure and material properties protect the brain during impact, we can design better preventative tools for humans. This work is in collaboration with Dr. Seth Donahue at UMASS Amherst.
Finite Element Modeling of Fiber-Reinforced Elastomeric Enclosures (FREEs)
This work, in collaboration with Dr. Keith Buffinton (also Bucknell Mechanical Engineering) and the University of Michigan aims to better understand how soft robotic actuators can be used as assistive devices.
