I grew up in Dayton, Ohio. I attended the University of Dayton where I started off majoring in Engineering. After the first year, I decided that Engineering classes weren’t for me, and that I really just enjoyed the math. So, I changed my major to Mathematics. At the end of my undergraduate education, I used my mathematics skills and participated in two different internships with the military. I quickly found that I did not like desk jobs, so I went to graduate school at Auburn University in Alabama.
My wife, Maria, and I lived in the Deep South for four years and became die hard Auburn Tiger football fans. We moved to Erie in 2010 and love being back in the North. It’s also great to be at a wonderful Catholic University like Gannon. Our first son was born in 2012, and he is definitely keeping us on our toes. We like to visit the Peninsula, the Erie Zoo, and Asbury Woods.
Three random bits of trivia about me: I have an identical twin brother. I have been sky diving and highly recommend it. In college I purchased a stuffed bison head that I still have today.

Most of my research has been in an area of Discrete Mathematics called Graph Theory. A graph is a mathematical object made up of points called vertices and lines that connect some of these vertices called edges. Specifically, I have done much work in Domination Theory.
I have also recently expanded my interests to include Design Theory and Number Theory. I have been working on cycle decompositions with long distance colleagues in Georgia and Ohio. I’ve also included undergraduates with some pretty interesting research, and I look forward to doing more of that at Gannon.
