about me
I am a research fellow in the Discrete Mathematics Group (DIMAG), which is part of the Pioneer Research Center for Mathematical and Computational Sciences within the Institute for Basic Science (IBS) in South Korea.
I work in graph theory with a focus on structural graph theory of both finite and infinite graphs and digraphs.
I obtained my PhD in mathematics from the University of Hamburg, under the supervision of Reinhard Diestel.
PhD Thesis: Connectivity and tree structure in infinite graphs and digraphs
