After graduating from Calvin College in 1971 I earned a Ph.D. from Northwestern University in 1975. I taught at Southern Illinois University from 1975 to 1985, and at Calvin College [now Calvin University] from 1985 to my retirement in 2014. During the Fall 2015 and Fall 2017 semesters I taught at LCC International University in Lithuania.
