The research of the Clinical Computational Neuroimaging group focuses on the development of quantitative neuroimaging biomarkers to improve the diagnoses, prognosis, management and ultimately outcomes of people with brain injury. We utilize state-of-the-art imaging acquisition and image processing techniques as well as advanced data analytics approaches including machine learning to achieve this goal. Below are brief examples of some of our research topics. More details can be found on our Publications page. Please feel free to contact us if you want more information about our research.

Neurologic Recovery after Cardiac Arrest

The goal of this research is to predict likelihood of good long-term neurological recovery in people who are initially in coma after experiencing a cardiac arrest. We combine advanced MRI techniques (diffusion tensor imaging, resting state fMRI, task-based fMRI) with EEG and clinical neurological examinations (such as the Glasgow Coma Scale and Coma Recovery Scale-Revised) to assess the extent of brain injury and likelihood of regaining consciousness. We apply graph theoretical analysis methods to assess the integrity of structural and functional brain networks.

  • Examples of alterations in brain diffusivity and structural connectivity in cardiac arrest patients who are comatose.

Traumatic Brain Injury

  • Mild TBI: Improve diagnosis and prognosis using MRI biomarkers

    resting state

  • Severe TBI: Prediction of long-term neurologic outcome using multimodal technique

  • Football Players Health Study

Quantitative Imaging Biomarkers

The goal of this research is to improve reproducibility and repeatability of MRI-based quantitative biomarkers.
