Mike Spivey

I am a math professor at the University of Puget Sound. My background is in operations research, although I also work in combinatorics. I teach typical OR courses such as optimization, modeling, and probability, as well as calculus, statistics, and differential equations.

My math blog, A Narrow Margin, includes (among other things) discussion of some of my favorite posts - of mine and of others - from math.SE.

My book, The Art of Proving Binomial Identities, includes many proofs similar to those I have posted on math.SE.
