I am a professor at Iowa State University and EditorinChief of the journal Order, published by Springer. My fields of interest are extremal poset theory, graph theory and extremal and probabilistic combinatorics. CV, Publications I was a Fulbright US Scholar as part of the Budapest Semesters in Mathematics program at the Alfred Rényi Institute of Mathematics, AugustDecember, 2019. I was also a visitor of Maria Axenovich at the Karlsruhe Institute of Technology, Germany via the German Academic Exchange Service Deutscher Akademischer Austauschdienst (DAAD), JanuaryMarch, 2020.
I am scheduled to teach M566: Combinatorial Optimization in Fall 2020. The textbook is Combinatorial Optimization, first edition, by Cook, et al. This is a printondemand book, so if you want a physical copy from the bookstore, be sure to order it at least 2 weeks in advance.
