Drs. Goldwasser and Letscher are on the Faculty in the Department of Mathematics and Computer Science at Saint Louis University. Both are active in teaching the introductory computer science course for which this book was designed. They have described the development of this material at the premier national and international conferences on Computer Science education. Dr. Goldwasser received his Ph.D. in Computer Science at Stanford University in 1997, and has taught courses at Stanford University, Princeton University, Loyola University of Chicago, and Colorado College before joining Saint Louis University. His research interests center around the design and analysis of algorithms. Dr. Letscher received his Ph.D. in Mathematics from the University of Michigan in 1997, and has taught courses in mathematics and computer science at the University of California San Diego, Oklahoma State University, and the American Institute of Mathematics before joining Saint Louis University. His primary research interests center around computational topology.
