Ben joined the Gettysburg College faculty in Fall 2007 after completing his Ph.D at Rutgers University. His primary research interests are in dynamical systems, especially differential equations with time delays. At Gettysburg, Ben has taught Math 107, 111, 112, 211, 215, 225, 315, 321, 331, 343, 361, 364, and 403, and a first-year seminar on automobile traffic flow. In his free time Ben enjoys playing jazz piano.
