Dr. Saul is interested in dynamics and neural control of the musculoskeletal system, upper limb biomechanics and orthopaedic rehabilitation, computational dynamic simulation of movement, and musculoskeletal imaging.

She directs the Movement Biomechanics Lab (MoBL), which investigates the relationship between musculoskeletal structure and function in the upper limb.  The lab uses MR imaging, strength assessments, and functional testing in conjunction with computational simulations of the upper limb to characterize and investigate upper limb function and neuromuscular control in healthy and impaired populations of subject

At the undergraduate level, Dr. Saul teaches Engineering Dynamics (MAE 208).

Outside of work, Dr. Saul enjoys spending time with her family, travel, being outdoors, and quilting.

Research Description

Dr. Saul’s research applies mechanical engineering techniques to improve treatment outcomes for neuromusculoskeletal disorders of the upper limb across the lifespan, using both computational dynamic simulation and experimental methods (including imaging, motion capture, and functional assessments of musculoskeletal performance). She uses computational simulation of muscle mechanics and the dynamics of functional movement to compare treatment options and predict functional outcomes; and explores muscle control strategies and movement compensations exhibited by healthy and impaired patients to provide a foundation for clinical practitioners to optimize rehabilitation for their patients. Recently, her work has focused on characterizing shoulder movement and neuromuscular control and compensations due to rotator cuff impairment in older adults and peripheral nerve injury in the upper limb. She is also interested in identifying general principles of scaling for upper limb musculoskeletal anatomy, useful for developing patient-specific approaches to clinical research.
