Mohamad El Hajj

Researcher, Programmer, Hiker and Calisthenics Athlete.

I'm a second year PhD student in the ECE Department at the Univeristy of Illinois at Urbana-Champaign, advised by Professor Christopher Fletcher and a member of the Security and Privacy Research at Illinois (SPRAI) group. I received my B.E. in Computer and Communications Engineering at the American University of Beirut, where I graduated with High Distinction.

My research interests are in system security, binary analysis, computer architecture and compilers.
