Dr. Steven Lay joined the Department of Natural Sciences and Mathematics at Lee University in the fall of 1998. An experienced college instructor, Dr. Lay came to Lee from Japan, where he served as a missionary for 8 years. Prior to his mission work, he was a professor of mathematics for nineteen years at Aurora University in Illinois, where he received the Excellence in Teaching Award in 1985. His M.A. and Ph.D. degrees in mathematics were earned at the University of California at Los Angeles. Dr. Lay teaches math classes at all levels from developmental to upper division courses for majors. He has written five books, including four math texts: Prelude to Algebra, Principles of Algebra, Convex Sets and their Applications, and Analysis with an Introduction to Proof. The 4th edition of his analysis book became available in the spring of 2005. His newest book, Japanese: Language and Culture, is used as a text in a one-semester introduction to Japanese course that he teaches each spring. Dr. Lay recently received a 3-year grant from the Tennessee Department of Education to train middle school pre-algebra teachers how to use operators in building a foundation for algebra.
