My main interests lie in neuroimmunology, cerebrovascular disease, neurocritical care, and the interactions between the central nervous system and peripheral organ systems (gut-brain axis, neurocardiology, etc.). My current research in the Loeb/Testai lab focuses on how intracranial bleeding drives neuroinflammatory processes which influence development of seizures and epilepsy. Using an endovascular perforation model of subarachnoid hemorrhage (SAH) coupled with long-term video EEG monitoring, I hope to understand how rupture of intracranial aneurysms plans a role in electrographic and cognitive impairment. I am also conducting various studies of inflammatory biomarkers in cerebrospinal fluid and serum samples from SAH patients admitted to our Neurosurgical ICU at UI Health.
