Broadly, I am interested in how the brain controls movement and how this process fails with disease. My research combines movement kinematics, functional neuroimaging, psychophysiology and cognitive neuroscience to uncover the neural basis of gait and cognitive-emotional interactions in health and disease. In particular, I aim to (i) investigate the complex interactions between cognition, emotion, gait and balance; (ii) leverage the complexity of gait control to expose subclinical predictors of aging and neurodegeneration for translation to clinical practice, and (iii) combine gait with innovative technologies, such as virtual reality and mobile recording devices, to catalyze early diagnosis, prevent gait disturbances and falls, and preserve mobility throughout the lifespan. This information can lead to improved strategies to better assess and manage gait disturbances and falls in older adults and individuals at risk and/or suffering from neurodegenerative diseases.
