Author Information

Andrew J. Hanson

is an associate professor of computer science at Indiana University. Previously, he worked in theoretical physics at a number of institutions and with the perception research group at the SRI Artificial Intelligence Center. His research interests include computer graphics, machine vision, perception, visualization of abstract concepts in mathematics and physics, and the design of interactive user interfaces for visualization applications.

He is a member of AAAI, American Physical Society, ACM Siggraph, IEEE Computer Society, and Sigma Xi.

Hanson received his BA in Chemistry and Physics from Harvard College in 1966 and his PhD in theoretical physics from MIT in 1971.

Tamara Munzner

is on the senior technical staff of the Geometry Center, a National Science Foundation Science and Technology Center at the University of Minnesota. Her primary research focus is the use of 3D computer graphics for mathematical visualization through interactive software and video production, for both research mathematics and the communication of mathematics to the general public. Her interests thus include interactive 3D graphics and user interfaces.

She is a member of ACM Siggraph.

While in school she worked at ETA Systems, the former supercomputer subsidiary of Control Data. Munzner received her BS in Computer Science from Stanford University in 1991.

George Francis

is professor of mathematics, super-computing applications, and the Campus Honors Faculty at the University of Illinois at Urbana-Champaign. His research interests include descriptive topology, numerical geometry, geometrical computer graphics, visual mathematics, dynamical systems, catastrophe and control theory, differential geometry and topology, riemann surfaces, low dimensional geometry and topology, history of the calculus and teacher education in science and mathematics. ``A Topological Picturebook'' of Francis' drawings by hand and computer has been translated into Japanese and Russian.

He is a member of SIAM and ACM Siggraph. Francis received his BSmcl from Notre Dame in 1958, an AM from Harvard in 1960, and the PhD in mathematics from the University of Michigan in 1967. We was a Woodrow Wilson Fellow in 1959, and a Lloyd Postdoctoral Fellow in 1968.
