Aquatic Propulsion
Currently working on an environment for the design and simulation of simple swimming creatures.

Plugmatch
A surgery assistance application with the Emory Orthopedic Center for Talus Osteochondral transplant planning. The surgery is a transplant of cylidrical bone and cartilage (plug) from one bone to another. We attempt to find and show the surgeon the ideal place to harvest from the source bone to best fit the destination.

Realtime Hair and Cloth Simulation
This project is an attempt to create a simulation of both hair and cloth that is not only real-time, but also convincing to the eye. Most hair and cloth simulations use a mass/spring setup, making length preservation and stability a concern. In my simulation, stability is guaranteed with no stretching of the hair (unless desired). The algorithm runs in linear time, only touching each mass once per time step.

GPU Ray Tracer
Implemented a ray tracer that runs entirely as a shader written in Cg based loosely on Purcell et al.'s paper Ray Tracing on Programmable Graphics Hardware.

TRING
This biliards game was created as a 3-week class project for an undergraduate graphics course with a classmate, Alex Powell. The game rules were given to us by Prof. Rossignac, so the project was to implement it using OpenGL. The physics are solved using a quartic equation to precisley predict all of the animation for an entire shot. This includes all acceleration, spin and collisions.

Digital Clay
Worked with Austina Nguyen (MS student in Mechanical Engineering) to implement a working interactive physics simulation of the "digital clay" surface. Her design was a deformable sheet that would smoothly interpolate control points (rods of varying height attached to the sheet).
