Below are my research papers, PDFs of a selection of the talks I have given, and my favorite .stl files for printing.

The files in this section are all of my own design, and almost entirely done in Rhino 3D on a mac. Please visit my shapeways store if you would like to order a model and have it shipped to you. If you have your own 3D printer, you can download the models here and print them yourself, for free! Please let me know if you do, I would love to hear your thoughts. If you don't have an application to view the models, below are links to Cura and Slic3r, both of which you can download for free and open .stl files in.
The following link is to OpenJSCAD, where I have written some code to let you visualize the Riemann sum of a function, and you can change the coefficients. There you can also download the stl file for it and print it yourself. It takes a few seconds to load the file.
