Research Interests

I am studying human motor behavior in the context of musculoskeletal pain and skilled performance. My dissertation studies focus on trunk control and attentional prioritization during gait in individuals with recurrent low back pain. Additionally, I investigate how dancer’s biomechanics change with skill level, lower extremity injury, and exertion. Together, my work will provide insight into the training and re-training of movement in a broad spectrum of populations.
