Our work links outward manifestations of pathology (e.g. functional deficits) with internal abnormalities (e.g. bone deformity, muscle dysfunction). We study how alterations to joint shape, muscle function, and movement patterns can detrimentally affect joint loading and lead to damage and osteoarthritis. Our studies combine tools within the categories of in-vivo biomechanics, medical imaging (e.g. CT and MRI), and subject-specific musculoskeletal modeling. By applying these tools in interdisciplinary teams with our partners in orthopaedic surgery, engineering, radiology, and physical therapy, we can improve surgical interventions, inform targeted rehabilitation, and enhance quality of life for people dealing with hip pain and osteoarthritis.

Current Research Studies
Longitudinal Changes After Periacetabular Osteotomy for Hip Dysplasia
Funding Source: NIH, National Institute of Arthritis and Musculoskeletal Skin Diseases (R01AR081881)
Developmental Dysplasia of the hip dramatically increases the risk for early hip osteoarthritis in adolescents and young adults and it is usually treated surgically with a periacetabular osteotomy. For some patients, outcomes after surgery are very good. Other patients have lingering pain and dysfunction. We are investigating how periacetabular osteotomy changes hip biomechanics and how those changes are associated with patients’ activity levels and self-reports of function, pain, and quality of life during the first year after surgery. Determining the longitudinal effects of surgery on biomechanics and how they relate to patients own perceptions of their recovery will inform new strategies to increase the proportion of patients with DDH who experience better quality of life and delayed osteoarthritis.
AI-assisted Image Segmentation and Surface Reconstruction of the Hip Across the
Lifespan
Funding Source: AI for Health Institute
This project is a collaboration between Engineering and Medicine to develop AI-assisted
segmentation tools using clinical scans and minimal user intervention, to improve
treatment for complex hip disorders. The project targets two major limitations of current
machine learning (ML) segmentation and 3D modeling methods: labor-intensive labeling
for training and validation, and the lack of ML models for young, skeletally immature
patients. Our goal is to build a lifespan hip model library for biomechanics and
development research and enhance surgical planning tools for hip preservation.
Current Members
We aim for our lab to be a stimulating environment where members conduct high-impact research, serve their community, and develop into top-quality scientists. Members of our lab have a variety of educational backgrounds, including biomedical engineering, mechanical engineering, computer science, exercise science, physical therapy, and kinesiology. We are often looking for undergraduates, graduate students, postdoctoral fellows, and research assistants.
