Research Summary
Dr. Nichols’ research broadly focuses on musculoskeletal biomechanics. The guiding vision of her lab is to create predictive simulations that cross disciplinary boundaries and improve the functional ability and quality of life for individuals with musculoskeletal disorders. In other words, she is actively working to create a future in which advanced computer simulations enable real-time, patient-specific prognostics in a doctor’s office. Toward this goal, her lab is pursuing (i) basic science projects focused on understanding musculoskeletal structure and function, (ii) computationally intensive projects to rapidly create personalized models and analyze predictive patient-specific simulations, and (iii) clinical projects focused on improving orthopaedic surgery and rehabilitation. All these projects integrate orthopaedic biomechanics, musculoskeletal computer simulations, quantitative medical imaging, and machine learning to understand both the patient- and surgeon-specific factors that influence musculoskeletal health.
