Research Scientist

I am a Threat Research Scientist on the Threat Intelligence team in Washington, D.C. Since joining Facebook in 2014, I have been studying the various threats targeting users across the Facebook Family of Apps, and coming up with impactful ways to protect them using novel techniques.

I hold a PhD in engineering and public policy from Carnegie Mellon University, and my thesis was on online crime modeling and prevention.
