His research focuses on discrete mathematics, particularly graph theory, with emphasis on graph coloring, structural properties of graphs, and combinatorial optimization. He investigates problems such as edge colorings, list colorings, and the coloring of graph products, contributing to both theoretical developments and algorithmic aspects.
Recent publications (2024–2025) reveal a consistent focus on edge coloring problems, including near-interval colorings, extensions of partial colorings, and the coloring of Cartesian products and hypergraphs. These works demonstrate a deep engagement with combinatorial structures and theoretical graph problems, often involving probabilistic and structural methods.
While no specific scientific awards are mentioned in the provided texts, his sustained publication record in high-quality journals such as Discrete Applied Mathematics, The Electronic Journal of Combinatorics, and Discussiones Mathematicae. Graph Theory underscores his active and respected role in the mathematical community.
He collaborates with researchers from Sweden and abroad, including Mesfin Masre, Fikre B. Petros, and Petros A. Petrosyan. Although no formal advisees are listed, his leadership role and publication collaborations suggest involvement in mentoring students and junior researchers. He is part of a vibrant research division with around twenty members, contributing to a dynamic academic environment.
The ALGD division conducts research in algebra, geometry, topology, dynamical systems, combinatorics, and graph theory. The graph theory group specifically focuses on classical problems with an emphasis on graph coloring and Hamiltonian graph theory, aligning closely with Casselgren’s research interests.
