Tom Hull is a leading expert on the **mathematics of origami** (paper folding) and has given talks on this topic all over the world. His research uses graph theory, combinatorics, geometry, and other areas of math, with applications in engineering, materials science, art, and education. He is the faculty advisor of the Math Club, he enjoys having students be involved in his research, and he teaches regularly in our graduate Masters in Mathematics for Teachers (MAMT) program. He also likes playing Ultimate Frisbee and reading supernatural horror.

Some of my publications can be found on the arXiv.

### Mathematics of Origami

Using math to understand the laws behind paper folding. This has applications in engineering, materials science, art, and education, as well as being an interesting math subject in its own right.

### Graph Theory

Studying properties of graphs (networks of points and lines), in particular graph colorings.

### Geometry

Euclidean, non-Euclidean, projective, and fractal geometry, especially as they apply to origami.

Undergraduate Courses: Calculus I, I, III, Linear Algebra, Modern Aspects of Geometry, Creative Problem Solving, Graph Theory, Combinatorics, Introduction to Modern Algebra, Real Analysis I, II, Complex Analysis

Graduate Courses (MAMT): Calculus Revisited, Creative Problem Solving, Discrete Mathematics, Geometry Revisited, Analysis, Algebraic Structures, Origami in Mathematics and Education, Topology and Fractals
