My research interests are developing methods for the analysis of medical images. My research focuses on creating parametric maps from post-reconstructed PET, SPECT, MRI, CT, and source localization EEG images. My current work focuses on improving parameter estimation using dynamic image noise reduction, segmentation algorithms, and the development of large image databases and specialized image search algorithms.
