Working as a PhD student researcher under my advisor Peter-Pike Sloan. We work on real-time lighting techniques for games and have published papers on Volumetric Obscurance at i3D 2010, and Modular Radiance Transfer with a sketch at Siggraph 2011 and a paper at Siggraph Asia 2011.

Worked under Kenny Mitchell as a summer intern at the now defunct Black Rock Studios. While there I implemented a version of Modular Radiance Transfer into their in-house animation tool, Tomcat. The video game scenes in our Siggraph Asia 2011 were created using my additions to that software.

Worked under Nathan Cournia at the film studio Rhythm & Hues implementing a variation on deep shadow maps (DSMs) using the GPU. The implemenation was written in GLSL as a set of shaders to be used in their proprietary animation system Voodoo. The DSM shaders allowed the artists to see shadow changes in real-time, instead of having to send their assets through the rendering pipeline. I also interfaced the DSM code with a simplified version of their fur shaders to assist with character visualization.

Worked as a researcher under Kadi Bouatouch along with Jonathan Brouillat and Christian Bouville developing a new global illumination sampling technique for ray tracing. Helped develop Bayesian integration techniques for global illumination by performing experiments using Matlab and proprietary rendering engines. These techniques were published in a paper published in Computer Graphics Forum.

Worked as a software engineer under Mark Kilgard to create a regression performance testing suite for the CG Toolkit runtime. Created a C++ test harness using OpenGL and DirectX 9 that ran CG and CGFX files to measure the performance of the CG runtime libraries. Included Python reporting capabilities which created gnuplot files to measure and compare performance results

Worked as a teaching assitant at the School of Computing at the University of Utah. I was a TA for for CS5610/CS6610 (OpenGL) under Dr. Charles Hansen and CS 2420 (Computer Science II - Java) under Dr. Peter Jensen. I was responsible for helping students with assignments during office hours as well as lecturing during discussion sections.

Worked for the Tools and Technology group extending and maintaining a domain specific language, called Domain, used for medical grouping and billing. The group was reponsible for compilers, debuggers, IDEs, and code generators for C, Java, Basic Assembler, and our own back end using a format called Knowledge Bases. I was reponsible for the Java and C runtimes as well as for creating a nightly build/test solution for programs using said language.

Worked as a test engineer on International medical Coding and Grouping software. I was responsible for the creation and running of manual as well as automated tests for COM+ based software in multiple languages. While there, I participated on a team to define database repositories of testing data for international and domestic medical records.

Worked as a programmer porting a set development tools from Windows to Linux. These tools consisted of a pre-processor for a converting an ADA like language into standard C as well as a personal make tool and shell. All programs were written in standard C.

Worked as a programmer to automate e-mail blast delivery processes using C++ and Visual Basic. Created e-mail scheduling programs as well as a program to automatically combine user data with form emails and insert them into an automated system based on SQL query statements.

Worked as a program tester for the Ensemble™ hard real-time simulation system at Evans and Sutherland. Duties included installing the program on multiple machines, running through the automated test program (ATP) and submitting bug reports.

Worked as a consultant doing on-the-spot web pages and small JavaScript programs dealing with fax and e-mail broadcasting. Web pages were done using Macromedia Dreamweaver and Fireworks, JavaScript was also used.

Programmed the SIRS Navigator, a Windows desktop application (created in Visual Basic) used by clients to browse the results of a compensation survey, view job data graphically, and generate job-pricing reports to support compensation planning and decision making.
