Dr. Petrosyan David
Research Director

David Petrosyan received the undergraduate and PhD degrees in Physics in Armenia. After a nearly three year postdoc stay in Israel, he was hired by IESL/FORTH, first on a tenure-track position and then a permanent position.
Dr. Petrosyan specializes in theoretical quantum optics and quantum information. He has published nearly 80 scientific papers and co-authored a textbook for graduate students.
