Working with Bill Thurston in 2011, we explored a process of making smooth surfaces in 3D from flat 2-dimensional rigid material such, specifically paper and craft foam. I gave a talk about this project in 2014 at the Thurston Memorial Confernce held at Cornell.

This project was with Lewis Campbell, a Master's student of Fatma Baytar in the Department of Human Centered Design. Together we making clothing with non-traditional seams from body scan data.

Harvard Preceptors Janet Chen and Stepan Paul developed class activities and 3D models for Multivariable Calculus in a project called Manipulative Calculus. With the support of Cornell's CTI micro-grant program  I 3D printed and thermoformed 240 models for use in Math 1920 at Cornell.

Together with Ithaca College undergraduate Sam Llyod, we experimented with approximating images by projecting them onto the span of a relatively small set of matrices that correspond to images. By decomposing the "basis" images into 3 or 4 sub-images, we were able to obtain recognizable approximations in a subspace with dimension less than 10% of the original matrix size.  Why did we do this?  To see what it looked like of course.
