He obtained a
B.S. in mathematics in 1971 from
University at Albany, SUNY,[2] and a
Ph.D. in mathematics in 1974 from
Rutgers University, with thesis Inequalities for the Ergodic Maximal Function written under the direction of Richard Floyd Gundy.[3] He 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 Mathematics 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 research work at the International Conference on Harmonic Analysis and Ergodic theory that was held in the name of Roger and his colleague
Marshall Ash.
Roger has since retired from teaching at DePaul and moved to Northern Wisconsin, where he teaches mathematics at
Conserve School.
