Ethan Rosenthal lives in New York City and is a data scientist at Square. Prior to Square, he freelance consulted and worked at some startups. Before doing data science, Ethan was an actual scientist. He got a PhD in Physics from Columbia University building atomic-resolution microscopes to study superconductors.

You can also find me on GitHub, Twitter, Mastodon, and LinkedIn. For the love of god, don’t contact me on LinkedIn.


Having suffered through years of dry physics talks during my academic days, I’m on a mission to give data science talks that are engaging and interesting while still delivering technical insights for the audience.
