Dr. Chuck Hansen has been awarded the 2005 Visualization Technical Achievement Award by the Visualization and Graphics Technical Committee of the IEEE Computer Society (IEEE VGTC). The award is in recognition of "seminal work on tools for understanding large-scale scientific data sets".
This is an international award and is the highest honor and recognition in visualization research. The IEEE VGTC started this award just last year, so Chuck is the second recipient of the IEEE Visualization Technical Achievement Award.
