Interests

I am interested in the development of new fMRI methods including advances in both image acquisition and image analysis. I am particularly interested in methods involving imaging at ultra high field (7T).

Projects

Currently, I have several parallel research paths I am pursuing. First, I am developing methods for pushing the spatial resolution of whole brain fMRI data. The goal of this project is to obtain images with the highest possible isotropic spatial resolution while minimizing geometric distortions of the images and maintaining reasonable temporal resolution. Second, I am developing methods for similarly pushing the temporal resolution of fMRI data while maintaining spatial resolutions similar to those typically used at lower field strengths. These acquisitions will be used for measuring cognitive latencies and validating methods for removing physiological noise.
