Jon Fickenscher is an associate research scholar and lecturer in the mathematics. He received his B.A. in Computer Science and Mathematics from the University of Texas at Dallas in 2006 and his Ph.D. in mathematics from Rice University in 2011. Starting at Princeton in the fall of 2011, Jon continues his research in ergodic theory and dynamical systems, specifically low-complexity models, and enjoys teaching courses such as calculus as well as upper division courses within the major. This fall, he is teaching Multivariable Calculus (MAT201) and will serve as course head. Jon's current research involves classifying dynamical properties of a system (what happens to a particle's trajectory in the long term?) by using combinatorial objects (how many disjoint loops can be drawn simultaneously in a given graph?). His teaching experience in Game Theory (MAT378) has also given him the privilege to act as adviser or second reader for the independent work of many talented majors. This position allows him to hear about their passionate applied work based in many of Princeton's other excellent departments such as Computer Science, Economics, Philosophy and Operations Research and Financial Engineering. Jon loves spending time with his family. With two children at home*, his free time is occupied with Legos, music, games and television with current emphases on Pokémon, SpongeBob SquarePants, cats and dogs. When able, he and his wife Amy enjoy trying and making new recipes and are always happy to hear about something new! *Some hobbies may or may not be entirely child dependent.
