Welcome to my web-page. I am a PhD student in the Machine Learning Department. I am currently working with Prof. Geoffrey Gordon. My current research focuses on building flexible models for dynamical systems. Previously, I worked on building probabilistic models for textual and social data.

Prior to joining CMU, I got my BSc and MSc in computer engineering from Cairo University, Egypt. My MSc thesis was supervised by Prof. Amir Atiya. While working as a teaching assistant at Cairo University, I was also an R&D engineer at IBM Cairo Technology Development Center and then a research assistant at Cairo Microsoft Innovation Center (currently known as Advanced Technology Labs Cairo) with Dr Kareem Darwish.


  • I sepnt summer 2014 in Google Mountain View as a software engineering intern, building models for user prediction.
  • I am TAing fall 2013 offering of 10701 (Machine Learning) with Geoff Gordon and Alex Smola
  • I spent summer 2013 in a Bing/MSR joint internship in Redmond
  • My paper with Avinava Dubey, Sinead Williamson and Eric Xing on non-parametric topic modeling over time has been accepted in SIAM Datamining Conference 2013
  • I spent summer 2012 in Bellevue as a Microsoft Research intern, working with Bing Document Understanding team.
