Best Paper Award and Honourable Mention at EuroVis 2025

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.

Markus Wallinger receives EuroVis PhD Award

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 researcher at TU Munich. Congratulations!

Thomas Depian receives State Prize for his Master's Thesis

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) in Sydney, Australia in December 2024. Congratulations, Thomas!

Welcome to our Feodor Lynen Fellow Dr. Frank Sommer

On June 1, 2024, Dr. Frank Sommer has joined the Algorithms and Complexity group with a prestigious Feodor Lynen postdoc fellowship from the Alexander von Humboldt Foundation.

Frank has received his PhD in 2022 from Philipps-Universität Marburg in Germany, and has worked as a postdoc researcher at Friedrich-Schiller-Universität Jena in Germany. In his one-year project at TU Wien he will investigate machine learning models such as decision trees and neural networks by exploiting specific input structures leading to input parameters which can be assumed to be small in practice. Together with his host Dr. Manuel Sorge, they will initially tackle these problems in theory by studying the parameterized complexity of these problems. Afterwards, they plan to implement the most promising algorithms they discovered.

Esra Ceylan won the OCG Award 2024

Our best Master thesis awardee last year, Esra Ceylan, won the OCG award 2024 for her Master’s thesis, supervised by Jiehua Chen! Congratulations!

The ceremony will take place at the Austrian Computer Science Day on June 14th:
