Tom Hull's Origami Research Corner
What is origami mathematics?
Origami is the art of folding paper. In the scientific research community, however, the word origami is being used to describe any kind of folding process. This could be strands of DNA folding inside a cell or in a lab (which can be modeled by 1-dimensional origami, like folding a string). Or it could be folding a flat solar panel array into a compact package that could be rocketed up into outer space (that would be 2-dimensional origami). Being able to design or control such folding mechanisms requires a deep understanding of how they work, and that's where the math comes in.
I am interested in all of the myriad ways in which mathematical methods can be used to understand folding processes, what I call origami mathematics. In this research I collaborate with many people. Some are mathematicians, while others are computer scientists interested in computational origami, engineers interested in folding mechanics, and physicics interested in origami applications in materials science.
On these pages you will find listings of current/past projects, collaborators, students, and funding sources for my research.

My new book, Origametry: Mathematical Methods in Paper Folding has just been published by Cambridge University Press!
This book offers an introduction to the mathematics of origami. It is organized into four parts:
See how origami is more powerful than straightedge and compass constructions.
The Combinatorial Geometry of Flat Origami
Here the rich field of flat origami theory is developed, with attention to the combinatorial structures that it contains.
Algebra, Analysis, and Topology in Origami
This contains examples of how various aspects of paper folding can be best modeled using either algebra (origami homomorphisms that capture the symmetry group of crease patterns and their folded images), analysis (how polyhedral origami folds can offer solutions to certain partial differential equations), or topology (folding compact manifolds in arbitrary dimension).
Three-dimensional, polyhedral origami is explored in this part, with particular attention to rigid origami, rigid folding motions, and configuration spaces.
