Research Description

Dr. Ay specializes in stroke and cerebrovascular disorders. Dr. Ay's research involves using imaging to investigate the clinic-anatomic-functional relationships in ischemic brain injury. Dr. Ay has developed various MRI-based methods to map clinical deficits using non-a priori anatomical hypotheses, to identify stroke etiology, and to predict tissue and clinical outcome following ischemic stroke and TIA.

Research interests

Transient ischemic attacks, neurocardiology, stroke recovery, and genetic and plasma markers of ischemic brain injury.

Research techniques

Statistical modeling of tissue and clinical outcome after ischemic stroke

Diseases studied

Stroke, cerebrovascular diseases
