Jeff Weeks is a freelance mathematician living in Canton, NY. He has an A.B. from Dartmouth College and a Ph.D. from Princeton University, both in mathematics. His thesis advisor was William Thurston. His main interests are geometry, topology, cosmology and education. After several years of teaching undergraduate mathematics, he resigned, and later began doing mathematical research and software development for the University of Minnesota's Geometry Center, designing and implementing software for creating and studying possible shapes for 3-dimensional space. His program SnapPea has been widely used by hyperbolic geometers and knot theorists.
A former MacArthur Fellow (1999-2004) and current National Science Foundation award recipient (2005-2008), Jeff splits his time between research and education. His present research centers on a collaboration with cosmologists with whom he is testing the shape of the universe using data from the Wilkinson Microwave Anisotropy Probe satellite. His educational activities have led to a multimedia unit for middle schools on geometry and space. The unit uses classroom activities, computer games and video to let students explore universes that are finite yet have no boundaries.
Jeff is the author of the book The Shape of Space (Marcel Dekker, 1985; second edition 2002), the unit Exploring the Shape of Space (Key Curriculum Press, 2001) and numerous research and expository articles.
