David Dempsey

Professor of Mathematics
137 Ayers Hall

Dr. Dempsey has been teaching mathematics at JSU since the turn of the century (2000), but JSU has always been a part of his life.  His parents, J. Wayne and Sharon Dempsey, both taught math at JSU, and he considers himself fortunate to have followed in their footsteps, aspiring to make a difference in the lives of his students, whether they are majoring in math, math education, computer science, or anything else.  Dr. Dempsey is a two-time alumnus of JSU, earning degrees in mathematics and music, and he was a resident in the International House during this time (1990-94).  In addition to teaching, Dr. Dempsey serves as faculty co-advisor for the JSU Math Club and Kappa Mu Epsilon (KME) National Mathematics Honor Society, as well as the National Treasurer for KME (2015-2023).  An avid musician, Dr. Dempsey is the staff organist at Jacksonville First United Methodist Church, as well as a member of the Calhoun County Civic Chorale.
