Bio Sketch

I am a Research Assistant Professor in the Department of Computer Science and the Center for Reliable Information Systems & Cyber Security (RISCS) at Boston University. I am a member of BU Security Group.
I also hold an adjunct research faculty position at Brown University's CS Department.

Before joining BU, I was a post-doctoral researcher in the Department of Computer Science at Aarhus University, Denmark, and in the Institute for Security, Technology, and Society at Dartmouth College.
I hold a Ph.D. and Sc.M. in Computer Science from Brown University and a diploma in Computer
Engineering and Informatics from the University of Patras, Greece.
