Isolated Cervical Spinous Process Fractures: Are They Associated with Instability or Neurologic Injury? – In a single center retrospective review of 18,126 neurosurgical patients at a major academic medical center from 2005 to 2012, 96 adult patients with isolated cervical spinous process fractures were identified and analyzed for the presence of deficits and surgical intervention. We suggest that these fractures warrant neurosurgical consultation to exclude neurologic injury or instability, but specific treatment or long-term follow up may not be required for most cases.
Serum Tau Levels as a Biomarker for Traumatic Brain Injury
– Initial investigation of the alterations in Tau expression as a result of mild TBI. Utilizing a pneumatic impact model we aimed to evaluate Tau expression serum levels following multiple injuries to elucidate the potential role of the protein as a biomarker for TBI.
Utilization of Human Neurons for Pre-clinical Testing of Novel Stroke Therapies
Analysis, revision, and discussion of a departmental human brain tissue protocol for submission to a book chapter. In it we provide a procedure of acquiring human neuronal cells and advocate the use of an in vivo model, as it possesses several advantages over current animal models in the realm of novel stroke therapeutics.

Role of Telmisartan in an Ischemic Stroke Model
-Through use of a transient middle cerebral artery occlusion (MCAo) mouse model we evaluated potential functions of Telmisartan. Pre-treated mice had smaller infarct volumes at 24 hours, and better behavioral performance compared to controls at 21 days. We concluded that telmisartan administered in the setting of acute stroke improves neurologic outcomes in our mouse model.
