About Me

I joined Carleton University in July, 2018. Currently, I'm part of the Institute for Data Science and the School of Computer Science. I got my PhD from the David R. Cheriton School of Computer Science at the University of Waterloo. I used to be part of the Data Systems Group, and I worked with this awesome supervisor. I got my master's degree from King Abdullah University of Science and Technology, where I worked with Panos Kalnis, who quit updating his web page because it's too mainstream apparently. I got my bachelor's degree from Alexandria University in Egypt.

Research Interests

I'm interested in all kinds of knowledge graphs and graph analytics topics. Especially, question answering over knowledge graphs and knowledge graph mining. I'm also interested in the problem of domain adaptation in machine learning. Finally, I'm also interested in supporting real-time analytics in sports.

Note to Prospective Students

If you're interested in joining my group, please take a couple of minutes reading this note, and Andy Pavlo's blog on how to write a bad statement before sending me an email. You know, just to avoid the disappointment.
