Joakim Blikstad wins 2025 EATCS Distinguished Dissertation Award

Can algorithms be both fast and simple? Joakim Blikstad has shown that they can. His PhD thesis from 2024 presented new combinatorial algorithms for solving some of the most fundamental problems in theoretical computer science. For this work, he has been awarded the 2025 EATCS Distinguished Dissertation Award.

The prize was presented at ICALP 2025 in Aarhus (Denmark) on 9 July 2025. Blikstad conducted this research at KTH Royal Institute of Technology in Sweden, where he completed his PhD in 2024. He is now a postdoctoral researcher at CWI’s Networks and Optimization group.

Blikstad’s thesis, “Matchings, Maxflows, Matroids: The Power of Augmenting Paths and Computational Models”, revisits classic augmenting-path methods to design faster and simpler algorithms for problems such as maximum flow, matching, and matroid intersection. These problems lie at the heart of combinatorial optimization and have been studied extensively for decades.

Joakim Blikstad’s work addresses a central question: can we develop efficient algorithms that maintain the combinatorial nature of these problems, rather than relying on continuous or algebraic techniques? He explores this question through new approaches that advance our understanding of these problems in modern computational models, such as parallel, dynamic, and online settings.

At CWI’s Networks and Optimization group, Blikstad continues to explore fundamental graph algorithms.

EATCS Distinguished Dissertation Award

The EATCS Distinguished Dissertation Award, presented annually by the European Association for Theoretical Computer Science (EATCS), recognizes outstanding doctoral theses for their originality, significance, and impact. In 2025, the award also goes to Christoph Grunau (ETH Zürich) and Tuukka Korhonen (University of Bergen). Each winner receives a €1000 prize, and their theses are archived in the EATCS online collection. Since 1972, EATCS aims to facilitate the exchange of ideas and results among theoretical computer scientists and to stimulate collaboration between the theoretical and the practical community in computer science.
