Associate Professor, School of Computing
Ph.D., University of Utah, 1987
Professor
Hansen joined the faculty in 1998.
His research interests span scientific visualization, computer graphics, and
high performance computing. Scientific visualization of large scale
problems is of key interest and recent work involves taking into
consideration time-varying data and exploiting this for speeding up the
visualization process. Other methods for visualizing large amounts of
data are multiresolution models and view dependent algorithms. The interest
in computer graphics is driven from the scientific visualization perspective
but includes parallel algorithms for speeding up global illumination.
