Biographical Information

Ehsan Chah graduated in 2007 with degree in Electronic Engineering from University College Dublin (UCD). His final year project was titled “Development of an automated seizure detection system for newborns using biomedical signal analysis”. He is currently conducting his research towards his PhD. His PhD is focused on understanding the neural code using electrophysiology recordings obtained from implanted electrodes.
