Zeinab Abbassi



I am a PhD student at the Department of Computer Science, Columbia University. My advisor is Vishal Misra. I am interested in problems related to social networks/media and (social) recommender systems.

I received my M.Sc. from the Department of Computer Science, University of British Columbia, Vancouver, and prior to that my B.Sc. in Computer Engineering from Sharif University of Technology, Tehran, Iran.
