Colorado College has another professor by the name of Siddoway, and you guessed it, the two of us are married. Mike teaches Mathematics. Maybe you've read through this whole page and are completely confused because you are looking for the Prof. Siddoway who studies module theory, commutative rings, computational algebra, and the history of mathematics!
