During graduate school at Indiana University, I studied triply periodic minimal surfaces with my advisor, Matthias Weber. My dissertation was centered on finding deformations of these surfaces. In particular, I proved that two minimal surfaces (the gyroid and the lidinoid) admit deformations. In the meantime, check out the Indiana University Virtual Minimal Surface Museum for tons of great pictures. (Click on "Archive".)

The gyroid is a triply periodic minimal surface that contains no straight lines or planar symmetry curvers. It was discovered by Alan Schoen in 1970 and was proven embedded by Grosse-Brauckman and Wohlgemuth (1995). The lack of symmmetries make the gyroid hard to visualize -- I think that the best way to understand it is to look at a rotatable 3-D model (or maybe to have a sculpture in your office). The gyroid has a host of physical applications, among them understanding ketchup, materials science, and modeling the microstructures of cells.
