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 Ktheory 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.
