Research Interests

My research examines the effects of brain injury and disease on functional brain organization. One primary goal of our work is to understand how distributed neural networks are altered following significant neurological disruption (e.g., traumatic brain injury).  Using functional MRI and high density EEG our work examines short-term plasticity during task acquisition (i.e., new learning) as well as whole-brain changes occurring during the first year after injury.  Two important facets to this work are the:  1) integration of network modeling (e.g., euSEM, graph theory) to document network changes and 2) focus on individual differences in recovery to address the heterogeneous effects of injury on neural systems.
