Cal Ribbens
Personal Background & Interests

I was born in Cadillac, Michigan on December 23, 1959. As a child I lived in Marion, MI; Lake Odessa, MI; Sauk Village, IL; and Burke, VA. I received a B.S. in Mathematics from Calvin College in Grand Rapids, MI, in 1981. My M.S. and Ph.D. in Computer Science are from Purdue University, in 1984 and 1986, respectively.

Outside of work, my time is spent with my family (wife Kathy, sons Philip and Michael, daughter Christina), my local church (Grace Covenant Presbyterian (PCA)), my kids' school (Dayspring Christian Academy), and rooting for the Hokies and the Chicago Cubs. And I will rarely turn down a donut or a bratwurst.
