MAJOR PROJECT EXPERINCE
Crowd Simulation and Rendering – Team – Research Project
Researching techniques for simulating 1000s of agents planning paths through 2D environments,
using Simulation Level of Detail, Clustering, Multi-agent Roadmaps, and RVOs.
Operating System (Distributed) – Individual – Class Project
Implemented, in C++, a basic operating system supporting multithreading, IPC, semaphores, and a
terminal device driver, all distributed across multiple computers.
Raytracer – Individual – Multiple Class Projects
Have written a raytracer that supports anti-aliasing, area lights, soft shadows, depth-of-field, global
illumination, and has a fast grid acceleration structure.
Processor Design – Group – Senior Design Experience
Designed a simple central processing unit on an FPGA. The processor had a 5 stage pipeline,
Instruction and Data set-associative caches, and other modern processor design concepts.
Molecular Dynamics System – Individual – Summer Work
Wrote a molecular dynamics based atomic simulator in C++. I also ported this code to a JAVA
applet to be integrated as a physics teaching tool.
Realtime Strategy (RTS) Game – Partner – Semester Long Project
Created a RTS using the advanced realtime graphics techniques including shadow maps, GPU terrain
LOD, Dynamics Imposters, vertex shaders, Skydomes, and a terrain-aware GPU particle system.
Go – Individual – Undergrad Thesis
Wrote AI that played the game of Go--the last traditional game which computers do not consistently
beat humans. I used an alpha-beta search on a subset of moves, and experimented with many
improvements such as the killer heuristic, the null-move heuristic, history heuristic, and negascout.
P2P File Sharing System – Partner – Class Project
Wrote an online peer-to-peer file sharing system in C#. This system used the gnutella protocol and
was able to autonomously find songs shared by other people, upload and download songs from peers,
and automatically continue interrupted partial downloads.
