Origami
Lang was introduced to origami at the age of six by a teacher who had exhausted other methods of keeping him entertained in the classroom.
By his early teens, he was designing original origami patterns.
Lang used origami as an escape from the pressures of undergraduate studies. While studying at Caltech, Lang came into contact with other origami masters such as Michael LaFosse,
John Montroll, Joseph Wu, and Paul Jackson through the Origami Center of America, now known as
OrigamiUSA OrigamiUSA (sometimes abbreviated as "OUSA") is the largest origami organization in the United States, with offices located at the American Museum of Natural History in New York City. It was founded in 1980 by Michael Shall, Alice Gray, Lillian O ...

s, and he became a sensation in the origami world when he successfully folded one after three months of design and six hours of actual folding.
In 1990, Lang first attempted to write computer code that would solve origami problems, and the result was his first version of ''Tree Maker''.
Lang takes full advantage of modern technology in his origami, including using a laser cutter to help score paper for complex folds.
Lang is recognized as one of the leading theorists of the
mathematics of origami. He has developed ways to algorithmetize the design process for origami,
and is the author of the proof of the completeness of the
Huzita–Hatori axioms.
Lang specializes in finding real-world applications for the various theories of origami he has developed. These included designing folding patterns for a
