2025-04 Thank you Google for supporting our research project through the Gemma 3 Academic Program!

2025-03 Google’s generous support enabled the purchase of two NVIDIA A5000 GPUs for our research. This valuable contribution significantly enhances our computational capacity at DCIC-UNS and ICIC (CONICET-UNS). Thank you, Google, for investing in academic research and education!

2025-02 Ana Maguitman participated in the Society-Centered AI Workshop organized by Google in Mountain View, from February 11 to February 13, 2025, where she presented a poster on our project. The goal of the workshop was to foster multidisciplinary collaboration and promote community-centered approaches to AI research and development.

2024-10 Our team is honored to have our project, Empowering Inclusive E-Deliberation by Harnessing Collective Wisdom and Minority Perspectives, selected as a recipient of the Google Academic Research Award Program. We sincerely thank Google for their support, which enables us to advance research at the intersection of AI, deliberative democracy, and inclusion.
