Hi, I’m Shelby Cox.
I am a postdoc in the Non-Linear Algebra Group at the Max Planck Institute for Mathematics in the Sciences. I work in algebraic statistics and use tools from tropical geometry, algebraic geometry, commutative algebra, and combinatorics. I am particularly interested in problems in phylogenetics.
I completed my Ph.D. at the University of Michigan with David Speyer in May 2024. I received my B.S. in mathematics and B.A. in linguistics from UMass Amherst, where I was advised by Jenia Tevelev.
Here is my CV (updated October 21, 2025).
At SIAM-AG 2025 I organized a mini-symposium on Phylogenetic Networks together with Max Hill, Annachiara Korchmaros, and Danai Deligeorgaki. See here for more details.
