My career has been focused on merging principles of clinical neurology and critical care medicine. My research focus is to identify neuroimaging biomarkers during the resuscitation phase of patients with acute brain injuries that are determinants of lesion repair, restoration of function, and recovery of consciousness. This has led to both in vivo & ex vivo investigations characterizing the MRI signature of primary microvascular injury after head trauma and other acute brain injuries.

Research Interests

I aim to become an independent investigator focusing on the pathobiology of TBI through the use of advanced MRI methods that can be translated to the care of critically-ill patients and used as outcome measures in clinical trials of new drugs and rehabilitation-based strategies to treat aspects of TBI—such as demyelination and neurodegeneration—for which there is currently no therapy.
