:"For Roger Jones the physicist and entrepreneur see Roger Jones (physicist and entrepreneur)"

Roger L. Jones is an American mathematician. He has his Ph.D. in mathematics from Rutgers University and has recently retired from a professorship in mathematics at DePaul University in Chicago. There he taught everything from remedial math to graduate-level courses. During his tenure at DePaul, Roger published numerous research papers in math, was awarded an excellence in teaching award, chaired the DePaul University Math Department, and was awarded National Science Foundation grants related to teaching mathematics. He has also worked with the Chicago Public Schools on improving math instruction.

Roger was honored for his work in Harmonic analysis and Ergodic theory at the "International Conference on Harmonic Analysis and Ergodic theory" that was held in the name of Roger and his colleague Marshall Ash. Information about that conference can be viewed here: [http://condor.depaul.edu/~haet/ Conference on Harmonic Analysis and Ergodic Theory]

Roger has since retired from teaching at DePaul and moved to Northern Wisconsin, where he teaches mathematics at Conserve School.
