About me

I received my PhD in computer science from UCLA in 2015. My doctoral dissertation introduced decomposition techniques to learn probabilistic graphical models from data more efficiently. I was honored to receive the Northrop-Grumman Outstanding Research Award.

Before UCLA, I visited LAAS-CNRS France where I enjoyed working with Dr. Pierre Emmanuel Hladik on stochastic analysis of real-time systems. Before that, I completed a Masters in computer engineering at Cairo University Egypt where I was extremely lucky to work with Prof. Amir Atiya. I was also a teaching assistant and a part-time research engineer at IBM.
