Musculoskeletal Biomechanics Lab

The human musculoskeletal system is a remarkable engineering system that enables voluntary movement with inherent ease in healthy individuals. Yet, its complexity makes it difficult to understand and treat many orthopaedic pathologies. We study musculoskeletal biomechanics in the context of injury and disease using motion capture, medical imaging, and computational modeling. Our ultimate goal is to integrate insights from our experimental and computational work in the development of effective rehabilitation strategies aimed at restoring and preserving pain-free mobility throughout the lifespan.

Assistant Professor, Mechanical Engineering

I am an assistant professor in Mechanical Engneering, with courtesy appointments in Biomedical Engineering and the Robotics Institute, at CMU and an adjunct faculty in Orthopaedic Surgery at the University of Pittsburgh School of Medicine. In Fall 2018 I established and now direct the CMU Musculoskeletal Biomechanics Lab, an interdisciplinary group seeking to understand and optimize movement mechanics in individuals with musculoskeletal pathologies.

Projects

Current projects in our lab focus on understanding how movement biomechanics in natural environmants relate to primary/post-traumatic osteoarthrits and poor outcomes following orthopaedic surgeries. We are developing tools to streamline patient monitoring out of the lab and assist clinicians with diagnostic, prognostic, and pre-surgical planning decisions. Additionally, we are collaborating with experts in sensing and haptics to develop portable systems for precision rehabilitation and evaluate them in natural environments.

  • Area 2

    Natural Environment Biomechanics

    The operational cost associated with traditional motion capture systems has inhibited clinical translation and discouraged large movement analysis studies. Recent advances in computer vision and wearable sensing offer untapped potential for movement analysis in natural environments, but the effectiveness of these technologies in estimating movement biomechanics within clinically tolerable errors remains limited. To address the shortfalls of current methods, we are working on new data-driven and physics-based approaches for estimation of clinically relevant outcomes from wearable sensors and video.

  • Area 1

    Role of Mechanics in Osteoarthritis

    Joint mechanics is a major contributor in the development of osteoarthritis and eventual joint failure, but this effect is highly variable across individuals given interactions between mechanical and biological factors. We study these interactions by evaluating cartilage response to different types of mechanical stimuli (e.g., natural loading, exercise, ligament tears) via medical imaging technologies. Findings from these studies should form the scientific basis of patient-tailored osteoarthritis prevention and rehabilitation strategies that are more effective than the current standard of care.

  • Area 3

    Precision Rehabilitation

    Injury prevention programs, disease-modifying interventions, and rehabilitation in orthopaedics currently require significant time investment from patients and medical staff, yet are not tailored to each patient. Our goal is to use insights from experimental and computational studies to design personalized interventions assisted by portable technologies and evaluate both their effectiveness in targeting a biomechanical outcome of interest in natural environments and their efficacy in modifying disease/improving rehabilitation. In this direction, we are collaborating with experts in sensing and haptics.
