Two papers co-authored by our ESPRIT fellow Sara Di Bartolomeo received awards during the EuroVis 2025 conference, held June 2-6 in Luxembourg. The Best Paper Award went to the paper “NODKANT: Exploring Constructive Network Physicalization” written by Sara together with her co-authors Daniel Paar, Henry Ehlers, Velitchko Filipov, Christina Stoiber, Wolfgang Aigner, Hsiang-Yun Wu, and Renata Raidou. This paper explores how constructing physical models of graph data can improve people’s understanding of complex information.

A second paper, “Optimizing Staircase Motifs in Biofabric Network Layouts​”, written by Sara Di Bartolomeo, Markus Wallinger,

Markus Wallinger, who did his PhD in the Algorithms and Complexity group in 2024, received the EuroVis PhD Award for his thesis “Exploring Graph-based Concepts for Balanced Information Density in Data Visualizations” last week during the EuroVis conference in Luxembourg. This year’s EuroVis PhD Award was awarded to three young researchers and recognizes outstanding dissertations in academic research and development on topics relevant to visualization. Markus’ thesis was supervised by Martin Nöllenburg and supported by the WWTF grant “Engineering Linear Ordering Algorithms for Optimizing Data Visualizations”. Markus is now a postdoctoral

Thomas Depian, Simon D. Fink, Alexander Firbas, Robert Ganian, and Martin Nöllenburg received the Best Paper Award for their paper Pathways to Tractability for Geometric Thickness [arXiv] at the 50th International Conference on Current Trends in Theory and Practice of Computer Science (SOFSEM) held in Bratislava, Slovakia from January 20-23, 2025.

Our former group member Markus Wallinger won the Award of Excellence by the Federal Ministry for Education, Science and Research. This state prize is awarded annually to 40 outstanding dissertations completed at all Austrian universities and in all subjects. Markus, as one of only four researchers of TU Wien, received this prestigious award on December 5, 2024 for his dissertation “Exploring Graph-based Concepts for Balanced Information Density in Data Visualizations”, supervised by Martin Nöllenburg. Markus is now a postdoctoral researcher at the Chair of Efficient Algorithms at TU Munich. Congratulations,

Our group member Thomas Depian won the Appreciation Award given by the Federal Ministry for Education, Science and Research. This state prize is awarded annually to the best 55 Master graduates among each year’s about 16.000 graduates of all Austrian universities. In 2024 Thomas, as one of only two students of TU Wien, received this prestigious award for his Master’s thesis “Grouping and Ordering Constraints in Boundary Labeling”, supervised by Martin Nöllenburg. Thomas will present the results of his thesis at the 35th International Symposium on Algorithms and Computation (ISAAC’24)

Markus Wallinger successfully defended his PhD thesis “Exploring Graph-based Concepts for Balanced Information Density in Data Visualizations” on April 26, 2024. Congratulations, Dr. Wallinger!

Markus was a PhD student in the Algorithms and Complexity Group and worked in the project Engineering Linear Ordering Algorithms for Optimizing Data Visualizations funded by WWTF. He was supervised by Martin Nöllenburg and his external thesis reviewers were Christophe Hurter and Stephen Kobourov. Markus will continue his academic path as a postdoc at TU Munich.

Soeren Terziadis successfully defended his PhD thesis “Algorithms for Schematic Representations” on January 9, 2024. Congratulations, Dr. Terziadis!

Soeren was a PhD student in the Algorithms and Complexity Group and was supervised by Martin Nöllenburg. His external thesis reviewers were Will Evans and Sabine Storandt. He is now a postdoctoral researcher at TU Eindhoven.

The 31st edition of the International Symposium on Graph Drawing and Network Visualization in Palermo, Italy, ended on September 22, 2023, with a large number of awards and prizes for members and students of the Algorithms and Complexity Group.

We congratulate Markus Wallinger and his co-authors Felix Klesen, Jacob Miller, Fabrizio Montecchiani, and Martin Nöllenburg for the best poster award 2023 on their poster “What happens at Dagstuhl? Uncovering Patterns through Visualization”.

Furthermore, the annual Graph Drawing Contest honored multiple contributions in the following categories:

Creative Topic: Board game recommendation graph. 15 international

Anaïs Villedieu successfully defended her PhD thesis “Engineering Human-in-the-loop Graph Drawing Algorithms” on July 24, 2023. Congratulations, Dr. Villedieu!

Anaïs was a PhD student in the FWF project “Human-centered Algorithm Engineering” and was supervised by Martin Nöllenburg. Her external thesis reviewers were Seokhee Hong and Philipp Kindermann.

Markus Wallinger, Alexander Dobler, and Martin Nöllenburg received the Best Paper Award for their paper LinSets.zip: Compressing Linear Set Diagrams at the 16th IEEE Pacific Visualization Symposium held in Seoul, Korea from April 18-21.
