About the Authors

Photograph of Mitch KellerMitchel T. Keller is the Associate Director of Undergraduate Studies in the Department of Mathematics at the University of Wisconsin-Madison. He was previously a tenured associate professor of mathematics at Morningside University. He holds a B.S. in mathematics from North Dakota State University and a Ph.D. in mathematics from the Georgia Institute of Technology. (His Ph.D. advisor is now his co-author on this book.) Mitch’s research interests are in the combinatorics of partially ordered sets, online algorithms, and combinatorial approaches to Stanley depth of monomial ideals. He likes to travel, bake, and take photographs. (The cover image for the 2016 Edition of Applied Combinatorics is of work his honors thesis student Matthew R. Kiser did on the board in Mitch’s office.) Mitch is also the Managing Director of the Mathematics Genealogy Project.

Tom Trotter photoWilliam T. Trotter is professor emeritus in the School of Mathematics at the Georgia Institute of Technology in Atlanta. In a career spanning more than four decades, Tom has been a faculty member and administrator at the University of South Carolina, Arizona State University, and Georgia Tech. He has published extensively on the combinatorics of partially ordered sets, graph theory, Ramsey theory, and extremal combinatorics. His monograph on dimension theory for partially ordered sets has been in print for nearly 25 years. Tom is an avid movie buff, fan of the New York Yankees, and golfer.
