## Meet our faculty.

Georgia Tech has faculty working in all areas of combinatorics, including probabilistic, extremal, algebraic, arithmetic, and graph theoretic. These faculty are in the School of Mathematics, the School of Computer Science, and the School of Industrial and Systems Engineering. Many of the faculty are affiliated with the ACO PhD program and the ARC research center.
