Rebecca Umbach

Originally trained as a criminologist, I now work on topics related to sexual exploitation and tech-facilitated abuse, including image-based abuse (NCEI) and CSAM. I am currently a staff UXR on the T&S Global Engagements Team. Before joining Google, I was a T32 postdoctoral scholar working with Dr. Nim Tottenham at Columbia University.
