In 2026 I graduated with a Computer Science PhD from UT Austin, where I was supervised by Etienne Vouga. During this time spent a lot of time thinking about applications of differential geometry and physics simulation to problems in computer graphics. Before that I designed and manufactured a microcontroller called the whoa board and developed algorithms for SLA 3d printing.

This website has been essentially archived. Go here for a personal site that I am more likely to keep up to date, and check google scholar for more recent publications.

The UT Austin CS department published a nice little article about some of our research here.

Please contact me if you've got a problem where my expertise might be useful. I am excited about lending my skills to interesting projects.

Integrable Symmetric Fields in Computational Design: From Stable Woven Shells to Seamless Parameterizations

Josh Vekhter

We explore foundational geometry processing problems related to the development of robust inverse design of periodic structures like stripes, weaves, and trusses, on complex geometric domains.
