This research is in the area of deformable dynamic simulations for computer animation,
specifically
passive simulation. One example of my work in this area is seen in the deformable
exercise mat shown. The active simulation of the vaulter feels forces related to the mat
based on a simplified model of the floor mat. Once the motion of the vaulter landing on the
simple mat is generated, this motion is used to animate the more sophisticated
deformable mat seen here.

Another example of using flexible spring mass systems is in clothing simulation. Like the floor mat, clothing is driven by the underlying simulation of the characters who wear them. Here are two examples I created, a shirt and a skirt. Both of these simulations appear in the animated short shown at the Electronic Theater at SIGGRAPH 96 in New Orleans Atlanta in Motion
