Timothy Sipka

I have been teaching at Alma College since 1979.  I have master’s degrees in mathematics, statistics, and computer science, and I thoroughly enjoy teaching courses in all three areas.  In addition to teaching, I organize the MATH Challenge, a team-oriented competition for undergraduates and the Alma College problem-of-the-month program for high school students.  Professionally my main interests include problem solving, graph theory, and the history of mathematics.  Outside of mathematics, my interests/hobbies include gardening, tinkering with cars, biking, and running.  I am married to Chris (the serious runner in our family), and we have three grown sons, Phillip, Stephen, and Mark.
