Nathalia Peixoto, PhD

I am an assistant professor of Bioengineering with the Electrical and Computer Engineering Department of GMU.  Until August 2006 I was a postdoctoral researcher at the Krasnow Institute, focusing on seizure control with low frequency electric fields.  I also developed microfabricated oxygen sensors to profile metabolic activity in cardiac cells at Stanford. During my PhD at USP (Brazil) I developed microelectrode arrays and investigated primary neuronal cultures. As part of my PhD project, I spent almost two years in Germany (in Bonn) as a researcher with the German Retina Implant project. During my Masters (at Unicamp, Brazil) I investigated the spreading depression phenomenon in the chicken retina.

My research interests include implantable electrodes and systems, hybrid systems (cell cultures and electronics), control of assistive technology, bioMEMS (bio-micro-electro-mechanical systems), and experimental models of neuro­pathologies such as epilepsy and spreading depression.
