Main Focus

My research focuses on human and AI cooperation in dynamic networks. I also have been working on information consumption in social media particularly along three dimensions of efficiency, trust, and divisiveness.

My research interests lie at the intersection of reinforcement learning, data mining, and social computing.

Curriculum Vitae

Since January 2021, I have joined the center for Human and machines at Max Planck Institute for Human Development as a postdoctoral researcher working with Prof. Iyad Rahwan.

January-December 2020, I was a visiting researcher in UCLA in LA, U.S. working with Prof. Jungsecok Joo.

I pursued my Ph.D. at Max Planck Institute for Software Systems (MPI-SWS) in the Social Computing Research group with Dr. Krishna P. Gummadi as my advisor.

I got my master degree in Artificial Intelligent at Sharif University of Technology, Tehran, Iran.
