Biography

I was born and raised in Damascus, the oldest continuously inhabited city in the world. I joined the computer science department at the University of Pittsburgh in 2006 for MS degree. Later on, I joined the PhD program and graduated in 2012. Currently, I’m a postdoctoral associate working with Dr Milos Hauskrecht on a variety of machine learning projects.
