Headshot of Yoel Roth

Hi!

I'm Yoel Roth, PhD.

I care about building technology that's resilient to threats and helps people and communities connect safely and authentically.

I’m currently a Knight Visiting Scholar at the University of Pennsylvania, a Technology Policy Fellow at UC Berkeley, and a Nonresident Scholar at the Carnegie Endowment for International Peace. My research and writing focus on trustworthy governance approaches for social media, AI, and other emerging technologies.

At Twitter, I was the Head of Trust & Safety, leading Twitter’s content moderation, integrity, and platform security efforts — including policy development, threat investigation, product, design, research, and operations.

Before joining Twitter, I received my PhD from the Annenberg School for Communication at the University of Pennsylvania. My research and teaching examined the technical, policy, business, and cultural dynamics of social networking and dating apps at the dawn of the “App Store” age.
