Professional Interests

I am interested in the visualization and quantitative analysis of MR brain data. I write the programs I develop in java so that the software can be used on a wide variety of computer hardware. The software is licensed under the GPL license, so researchers around the world can build on my work. I am interested in taking advantage of the recent advances in graphics hardware to enable complex, high-quality real time visualization of brain data.
