Welcome to my collection of articles. My name is John Lenz and I am currently looking for jobs (I just finished my postdoc as a research assistant professor at the University of Illinois at Chicago). My interests are mathematical computer science and programming: machine learning, graph theory, extremal combinatorics, algorithms, complexity theory, Haskell, and many more.
