Research
My main area of research focuses on general techniques for
improving performance of out-of-core visualization of
multidimensional scientific data. I follow two directions in
improving processing speed. First, I use knowledge of the
storage order of data on disk and knowledge of data access
patterns required by the visualization algorithm to optimize
disk access. Second, I create multiresolution or adaptive
resolution representations of data and I use the low resolution
version of data for building a representation of the entire
data-set, and I use the high resolution version of data only
for visualizations of small regions of interests. I am
especially interested in using my work and general
visualization algorithms in medicine. This resulted in a
colaboration with Dr. Felix Hamza-Lup
for the development of a planing tool used for early detection
of collisions in radiation treatment of cancer patients.
