Omer Oralkan

Bio

Dr. Oralkan joined the faculty at the North Carolina State University in January 2012. His research interests are at the interface of electrical engineering and the life sciences, particularly on using integrated circuits and underlying technologies to implement medical devices and supporting systems for diagnostics and therapy. More specifically, his current research focuses on developing devices and systems for ultrasound imaging, photoacoustic imaging, image-guided therapy, biological and chemical sensing, and ultrasound neural stimulation.

Prior to joining NC State, he was a Research Associate (2004-2007) and then a Senior Research Associate (2007-2011) in the E. L. Ginzton Laboratory at Stanford University, where he worked on capacitive micromachine ultrasonic transducers. He also served as an Adjunct Lecturer in the Department of Electrical Engineering at Santa Clara University, CA (2009-2011).
