Research Scientist/Engineer

I am a research scientist/engineer at Facebook focusing on abuse problems. I’m currently a Tech Lead on the External Data Misuse team, working on efforts to stop scraping and automation. I have published numerous academic papers on aspects of computer security and recently co-authored a book on Machine Learning and Security, published by O’Reilly. I hold a PhD in mathematics from UC Berkeley and did postdoctoral research in cryptography and security at CWI and Stanford University.

Interests

Social network abuse (fake and compromised accounts, spam), scraping prevention and bot detection, adversarial machine learning, and measurement and experimentation for abuse problems
