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 was a Fulbright US Scholar as part of the Budapest Semesters in Mathematics program at the Alfred Rényi Institute of Mathematics in 2019. I was also a visitor of Maria Axenovich at the Karlsruhe Institute of Technology, Germany via the German Academic Exchange Service (DAAD) in 2020.
