INTERNSHIPS AND VISITS

• Dec. 14-23, 1995; Visited Dr. D. Rottenberg's PET Imaging Services in the Dept of Neurology at the VA Medical Center, Minneapolis, MN. Worked on Fractal approximations of images and Fractal metrics for quantitative analysis of image similarities;
  
• May 05- June 16, 1996; Internship at the PET Imaging Services , Dept. of Neurology, VA Medical Center, Minneapolis, MN. Worked on Segmentation and Partitioning schemes for Human Brain (anatomical and functional) data analysis, and improved on a Fractal algorithm for image magnification;
  
• Aug. 12-18, 1996; Visiting Dr. Chin-Tu Chen at The Frank Center for Image Analysis , The University of Chicago, Chicago, IL. Worked on a Transformation approach for analyzing medical images (brain scans). Also made progress on designing warps using the Discrete Fractal Transform, and classifying warp transformations obtained by using other techniques.
  
• May 01 - Aug. 01, 1997; Visiting the Laboratory Of Neuro Imaging, LONI , Division of Brain Mapping, Medical School, University of California at Los Angeles. Worked with Arthur Toga, Paul Thompson, Roger Woods, Michael Mega, Colin Holmes, Sanjaya Saxena and others on two projects: "Probabilistic Sub-volume partitioning techniques for determining the statistically significant regions of activation in stereotactic functional data"; and "Quantitative evaluation of stereotactic polynomial warping techniques".
  
• August 10-25, 1997 Visited PET Imaging and Department of Neurology at the VA Medical Center, Minneapolis, MN. Worked on a wavelet-based quantitative evaluation of non-affine registration techniques developed by Kjems et al. [1997].
