Proud of Denisa Arsene for presenting us and our work at the Complex Networks conference last week. She had a lot of engagement during her presentation, and made a ton of cool new science friends from all over the world 🤓 🌟

Key contribution: SANA (simulated annealing for network anonymisation), an algorithm that makes small alterations to social networks to protect the people in the network from de-anonymization attacks.

Motivation: Facilitating data sharing between social scientists while preserving the privacy of the people who were part of those studies.

More info, including preprint and poster (with ALT): latower.github.io/posts/2025/1

Denisa presenting her poster to another conference-goer. She is pointing excitedly to the part of the poster that summarises the finding that our new algorithm has the same running time as the state of the art and retains the same utility value, but performs much better in terms of anonymisation.Denisa posing next to her poster.
