J.M. Berger has authored and co-authored several groundbreaking studies on social media analysis, including the development of metrics for measuring influence, community detection and detecting the use of manipulative tactics online.

Berger's research informs his latest book, Optimal, a dystopian novel that "skewers reliance on social media" in "a sharp, gripping story of a bleak future," according to Kirkus Reviews.
