About Me

I am a senior robotics researcher at Waymo. I received my PhD in Computer Science from UCLA where I was a member of the Automated Reasoning Group. 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.

My research interests are in:

  • machine learning
  • automated reasoning
  • optimization

I am particularly interested in the design and analysis of highly efficient and accurate deep models which are trained using supervised, reinforcement or imitation learning. On the practical side, I focus on the development of efficient and theoretically sound reasoning algorithms that can work in real-time.
