After completing his PhD at Brown University in Mathematics (supervised by Dan Abramovich), Noah was a postdoc at University of Zurich in Switzerland and then at U.C. Berkeley (mentored by Bernd Sturmfels). He held tenure track positions at University of Georgia and Swarthmore College while he and his wife, a musicologist, looked for academic positions near each other, which they ultimately found in the Boston area. Noah's academic training was in pure mathematics, specifically algebraic geometry (the abstract study of systems of polynomial equations and their solutions), but in recent years he has also become involved in data science and exploring interactions between mathematics and legal studies. He created and runs an NSF funded high school enrichment program called "Math and Law Day" where students learn about mathematical and statistical topics that have entered the courtroom. In his data science research, he is particularly interested in using, and developing, geometric tools to uncover structure in data.
