Jeff Lait is a senior mathematician at Side Effects Software where he has worked on Houdini since version 1.0. He has contributed to geometry processing, rigid body solvers, and fluid simulations. He has also had the "joy" of working with many architectures over the years: SGI, Alpha, x86, Itanium, PS2, and PS3; and is still waiting for the system that solves more problems than it causes.
