Rebecca Sorla Portnoff (n‌‌ée Pottenger)

I am a Research and Data Scientist at Thorn. I am also a PhD Candidate at UC Berkeley finishing my dissertation this fall, advised by Dr. David Wagner. My dissertation focuses on using Machine Learning and Natural Language Processing to analyze, classify and identify criminal elements on the Dark Net, with a special emphasis on human trafficking and child sexual abuse. In my work, I seek to build tools and techniques that can empower investigators to seek out and find the marginalized children who are exploited, taken advantage of and abused.
