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.

At Twitter, I'm the Head of Site Integrity and Director of Trust & Safety. I lead Twitter's policy and threat investigation teams working on security, authenticity, and content policy issues.

Here's what I've been working on lately:

As we’ve built out our policies on misinformation over the last 18 months, we’ve been studying where and how reporting can help us identify harmful content faster. Today, we’re launching a new test for people to report potentially misleading Tweets 👇 https://t.co/tHtvd6gkvt

Twitter’s misinformation labels are too obscure and hard to see.
