About Me

I am a computer science researcher, with focus on Social Network analysis, Cyber Security and software development. I hold a PhD in Computer Science from the Ben Gurion University of the Negev in Israel, and a Master degree in Computer Science from the Open University in Israel. My PhD field of expertise is information security on social networks. I taught for many years at different academic institutes on Israel, and a worked as a freelance in Cyber Security research and analysis, web solutions and software development. My current research focuses on detecting and preventing Fake News on Social Networks.

Research Interest

Computer Science; Online Social Networks security; Fake News Detection; Privacy; Cryptography; Smart traffic control.
