grew up in Brooklyn and received his B.S. in Mathematics from Brooklyn College in 1976. He received his M.S. in 1977 and Ph.D. in 1981 from the University of Chicago. His DePaul career began in 1981, where he continues to do research in the branch of abstract algebra known as noncommutative ring theory. For the last 15 years, much of his teaching, research, and service activities have dealt with improving the preparation of high school mathematics teachers. He and his wife Donna have four children and five grandchildren. When not doing mathematics, he is probably watching baseball or a formulaic drama series.
His research has received external support from the English Speaking Union, the National Science Foundation, and the National Security Agency. He has given lectures in 7 countries and co-authored papers with 16 mathematicians around the world. For twelve years, he was a member of the Maine Township District 207 School Board and served one term as president. He assisted in the creation of the School Based Health Center at Maine East High School and served on their Advisory Board for six years.
His textbook A Concrete Approach to Abstract Algebra was published in 2010 by Elsevier. In 2001, he received the Excellence in Teaching Award from the College of Liberal Arts and Sciences and, in 2007, received their Cortelyou-Lowery Award for Excellence.
