Professor Dean received her Ph.D. in mathematics from the University of Massachusetts, Amherst, and she attended the Institute for Retraining in Computer Science at Clarkson University, a program that trained mathematicians to teach computer science at the college level. She shares her position in the department with her husband, Gove Effinger. Prof. Dean's teaching is influenced by her research interests, which include graph theory and computational geometry; she most frequently teaches “MC” courses, which focus on material on the borderline of computer science and mathematics. Prof. Dean has over twenty-five publications and has worked with more than twenty co-authors. Her publications include three research papers co-authored with undergraduates and a college textbook on programming in QuickBASIC that was co-authored by Prof. Effinger. In 2010 Prof. Dean received “the highest honor that the Skidmore faculty can bestow on one of its own,” the Edwin M. Moseley Lectureship, in recognition of her scholarly achievements.
