Hi, I’m Dan Shiebler. I like math, history podcasts, fantasy novels, riding my bicycle, and traveling. I live in NYC.

Today I work as the Head of Machine Learning at Abnormal Security. I lead our team of 40+ detection engineers to build AI systems that fight cybercrime. We use a combination of foundational data engineering and advanced ML to detect and remediate cyberattacks. Our technology protects many of the world’s largest companies.

Previously, I managed the Web Ads Machine Learning team at Twitter. Before that I worked as a Staff ML Engineer at Twitter Cortex and a Senior Data Scientist at TrueMotion.

I’ve also spent some time in Academia. My PhD at the University of Oxford focused on applications of Category Theory to Machine Learning (advised by Jeremy Gibbons and Cezar Ionescu). Before that I worked as a Computer Vision Researcher at the Serre Lab.

I Tweet @dshieble and my linkedin and github are usually somewhat up-to-date.
