Research Interests

1) Develop clinically-relevant evaluation and intervention strategies to reduce risk of lower extremity injury in at-risk individuals during activities with and without load carriage. Ideally, evaluation and interventions can be performed in-field to maximize ecological validity while minimizing training disruption. Key populations of interest include runners and tactical athletes.

2) Address aberrant movement strategies and musculoskeletal properties that may place individuals at risk for impaired gait performance and the eventual development of knee osteoarthritis. Specifically, individuals who are post-partial meniscectomy or post-Achilles tendon rupture the subject of this research focus. This focus aims to improve musculoskeletal function to maximize physical activity levels across the lifespan.
