Biography

I grew up in Alliance, Ohio, two hours southwest of Erie. I joined the Department of Mathematics here at Gannon in 1999.  My wife Kristin and I celebrated our 25th anniversary in the summer of 2017.  We have two college-age children and two extremely silly shih tzus.

My Ph.D. is in the area of algebraic combinatorics. Combinatorics is the mathematics of finite sets - think about problems like counting the number of possible lottery tickets, or constructing a schedule for a sports league. Algebra, especially matrix algebra, is a source of both questions and solutions in combinatorics. More recently I have become interested in statistics for the variety of modern techniques and computational tools that are being applied in seemingly every field of knowledge. 

My biggest claim to fame on campus is probably my appearance as a contestant on Who Wants to Be a Millionaire? in 2004.  I was also a contestant on Jeopardy! as a graduate student, and I’ve written articles about the mathematics of both shows for Math Horizons.  I am fascinated by history and love music from classical to jazz to rock.  I am a life-long Cleveland fan who is also intrigued by international sports such as soccer and cricket.  I have been fortunate to do much traveling.  Two places particularly special to me are Japan, where my wife once taught English, and the Great Lakes region as a whole.  I have lived in Michigan and Ontario and along Minnesota’s Lake Superior shore, so I have seen the lakes from all sides and discovered many wonderful spots along the way.
