Recently, I finished my Ph.D. thesis, "Measurement and visualization of white matter fascicles using magnetic resonance diffusion-weighted imaging fiber tractography", at Stanford University. I was extremely fortunate to have been advised by two great mentors at Stanford: Sandy Napel (Radiology) and Brian Wandell (Psychology). Other professors that I owe a great deal for their mentorship and many hours spent working with me at Stanford include Pat Hanrahan (Computer Science) and Art Owen (Statistics) 
My first research passion was the development of interactive scientific visualization and measurement tools that focused on enhancing experimental control and intuitive manipulation of data. A few years later, my second passion became using these tools to measure properties of the white matter in the brain. Neuroscience My research interests in the brain are focused on measuring properties of the brain's white matter using diffusion-weighted MRI. My exploration in this area began as a project to develop visualization software (DTI-Query) that facilitated interactive exploration of hypotheses about connectivity using fiber tractography. After this work, I introduced two of my own algorithms for fiber tractography: Connectivity Tracking (ConTrack) and Fascicle Tracking (FascTrack). Earlier Visualization Software Research As one of my first projects at Stanford, I combined various standard visualization techniques to understand their utility for enhancing radiologist performance when interacting with a proposed computer automated detection system for lung nodules within CT volumes. I was advised by Geoff Rubin and Sandy Napel during this work.

ConTrack - Software for identifying the most likely pathways of white matter between regions in the brain using diffusion imaging fiber tractography DTIQuery - Software for exploring connectivity in human brain white matter using diffusion tensor imaging, tractography and dynamic query techniques VISTASOFT - Tools for vision and imaging science. I have made several contributions to this toolkit and most notably to the DTI analysis tools. Stanford University Radiology Framework (SURF) - Framework for rapid development of visualization applications for clinical study. Fiber Shape Analysis - Software for performing clustering and shape analysis on potential neural pathways retrieved from tractography on diffusion tensor imaging data. This software was a class project for a course I took in applied multivariate analysis taught by John Kettenring. I won the book "An R and S-Plus Companion to Multivariate Analysis" by Everitt for this project. Virtual Navigation Bronchoscopy Suite (VN) - Used for planning bronchoscopic procedures and guidance during bronchoscopy. Focused on a unique method for fusing acquired bronchoscopy video with previously acquired computed tomography images.
