Tai-Danae Bradley

I am a sixth-year PhD student in mathematics at the CUNY Graduate Center under the supervision of John Terilla. In Summer 2020, I will begin as a postdoctoral researcher at Alphabet's X, the Moonshot Factory. My current work lies in the intersection of quantum physics, machine intelligence, and category theory. Below is a list of my research and publications.

PhD Thesis

At the Interface of Algebra and Statistics
My thesis uses basic tools from quantum physics to investigate mathematical structure that is both algebraic and statistical. arXiv: 2004.05631, introductory video
