Computational social scientist studying the media information ecosystem. Now postdoc @NorthwesternU, previously PhD @Penn.

Joined September 2012
Replying to @csspenn
@csspenn has released a new dataset of 140,000+ news articles from the 2024 U.S. presidential election year, providing a new resource for studying how news coverage is selected and framed, published in @ScienceMagazine. The Penn collaboration includes @annenbergpenn and @wharton and is led by @DuncanJWatts. “We can't measure bias directly, but we can see its imprints,” says Watts. bit.ly/3V5J3cV

New paper out in @ScienceAdvances! News organizations shape public understanding through the choices they make about what to cover and how to cover it. How can we measure these differences across publishers systematically and at scale? We present the Media Bias Detector!

This project has been a huge undertaking spanning more than two years and would not have been possible without an amazing team of collaborators at @csspenn: @Amir__Tohidi, @jennyshwang, @Timothy95Doerr, @DavMicRot, Chris Callison-Burch, and @duncanjwatts!

Congrats @samarhdr! We are all so proud of you and what you've accomplished.
Congratulations, Dr. Samar Haider! 🎓🖥️ @samarhdr Samar successfully defended his dissertation, "A Computational Approach to News Production", studying how computational methods can help us systematically understand what news organizations choose to cover and how they cover it.

Everybody trivializes common sense because we believe it is self-evident and universal. But is it really? Find out by participating in our Common Sense Project: commonsense.seas.upenn.edu. With @AmirhosNakh, @MarkWhiting, and @DuncanJWatts at @CSSPenn. 1/n
