This will be Silas' fourth time teaching at MathPath.
Deborah Kent
Senior Lecturer in History of Mathematics
St. Andrews University, Scotland

Prof Kent was formerly on faculty at Drake University, where she enjoyed teaching a wide range of mathematics courses and the occasional class in her speciality, the history of mathematics. She is transitioning this summer to a new position at St. Andrews. She's always on the lookout for a colorful classroom narrative or a chance to incorporate 3D printing in class. Her current research passion is 19th–century solar eclipse expeditions. (Mark your calendars for 2024!) Prof. Kent won an MAA Halmos–Ford award for expository writing and Technology Association of Iowa Academic Innovation and Leadership Award in 2017. She was selected as Drake A&S Professor of the Year in 2018. Prof. Kent is excited to draw on material from her recent AMS Game Theory book in her second time teaching at MathPath!
Asia Matthews
Quest University, British Columbia, Canada

Asia has been teaching at Quest University in Canada since 2014. Her primary professional interest is mathematics education, specifically problem design, creativity and communication. 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. This will be her third year at MathPath.
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 third year at MathPath. Her outside interests include swing dancing, board games, hiking and photography.
Lara Pudwell
Associate Professor of Mathematics and Statistics
Valparaiso University

Professor Pudwell studies enumerative combinatorics, which means she loves to count! Her work usually involves counting permutations with special properties. She is a winner of a national teaching award from the Mathematical Association of America (the 2014 Alder Award). For the past decade, most of her summers have been spent directing the Valparaiso Experience in Research by Undergraduate Mathematicians program, and she really enjoys working on new problems with students.
