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.
