Our goal is to develop an optical (non-invasive) method of in vivo surface analysis of brain tissue to replace the current method of using arrays of electrical probes to localize the focus of the seizures and direct surgical intervention.  This work is in collaboration with the Schwartz group at the Weill Cornell Medical College of Cornell University.

In this research we demonstrate a reflectivity-based perfusion sensor comprised of surface mounted light emitting diodes on a flexible substrate with integrated photodetectors in a form factor suitable for direct brain contact and chronic implantation.

Research is ongoing, but initial results are promising!
