Herng Yi

I'm a student at the Massachusetts Institute of Technology. As an amateur math enthusiast, I've been researching the mathematics of origami for ~5 years. I also enjoy presenting pretty math to anyone who will listen.

For a preview of my research, see: http://www.sciencedirect.com/science/article/pii/S0010448511003058
