Since April 2018, I have joined the Computational Social Science department at GESIS - Leibniz Institute for the Social Sciences as a postdoctoral researcher. January-March 2018, I was a visiting postdoctoral fellow in 'Algorithmed Public Spheres' network at Hans Bredow Institute for Media Research at Hamburg University, Germany. 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.

My research focuses on studying how users are consuming news and information on online social media and in evaluating the role played by automated retrieval algorithms, like search and recommendation systems, in shaping the users' news & information consumption. I have developed frameworks for measuring the bias and diversity in the news and information that users are consuming via algorithmic recommendation and search systems on web and social media platforms.
