I am a professor at Iowa State University and Editor-in-Chief 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 am a Fulbright US Scholar as part of the Budapest Semesters in Mathematics program at the Alfred Rényi Institute of Mathematics, August 12-December 29, 2019. (Click here for local BSM info.)

I will be visiting the Karlsruhe Institute of Technology, Germany in the spring of 2020 via the German Academic Exchange Service Deutscher Akademischer Austauschdienst (DAAD)
