She is also interested in discrete mathematics, especially combinatorics, the geometry of paper folding, and the history of mathematics. She has been involved in a number of mathematics outreach programs for elementary and high school students and their families. She finds joy in teaching people what it is to think mathematically and to develop and communicate their own mathematical ideas.
Stephen Maurer
Professor of Mathematics Emeritus, Swarthmore College, Swarthmore PA
Executive Director, MathPath

Professor Maurer is a long-ago Chair of the American Mathematics Competitions (in the 1980s!), co-author of "Discrete Algorithmic Mathematics" and "Contest Problem Book IV", and an expert on mathematical writing, in which he has instructed "MathPathogens" for many years through discussing their solutions to the Qualifying Test. He also taught breakouts on mathematical induction, on combinatorics, and on something he named Linear Set Geometry. Among his various hobbies is zip codes. He used to be able, if you told him where you lived, to tell you your zip code within 5.
   Unfortunately, he has Parkinson's Disease, and in the last 4 years, it has gotten much worse. This summer for the first time he is not able to attend the whole camp, but he does intend to beam in regularly, to continue the behind-the-scenes work necessary for MathPath to run, and he very much hopes to make it to camp for the final week, to meet all of you students he admitted, and to give the writing plenaries that week. The photo shows him last year, using technology to give his plenaries while seated – he would much prefer to be standing at a blackboard using his beloved colored chalk. If he comes to camp, he will need your help and understanding.
Kathryn Nyman
Associate Professor of Mathematics, Willamette University

A combinatorialist at heart, Professor Nyman enjoys counting visually appealing objects, such as graphs, partially ordered sets, and colorings. She also has a fondness for the mathematics of decisions and preferences, and she works on questions in voting theory and fair division. She is a recipient of the Clark Distinguished Teaching Award from Cornell University (where she did her graduate studies). This is Professor Nyman's second year at MathPath, and she is especially excited to be here. Her outside interests include swing dancing, board games, hiking and photography.
