Paul Siegel

I am a data scientist building statistical / machine learning models with social media data at Brandwatch .

Formerly: I got a PhD in math at Penn State in operator algebras; my thesis involved applications of K-theory for operator algebras to geometry and topology. I spent 3 years as a postdoc at Columbia University.

I have a math blog , but I don't write for it nearly often enough.
