Romeo Passaro

Romeo Passaro is an Italian mathematician and machine-learning researcher. He represented Italy at the International Mathematical Olympiad in 2020 and 2021, earning a silver medal in 2021. He studied Mathematics at the University of Cambridge (BA 2021-2024; MMath 2024-2025) and is a DPhil (PhD) student in Computer Science at the University of Oxford. He is also a Predoctoral Fellow at AITHYRA, the Research Institute for Biomedical Artificial Intelligence of the Austrian Academy of Sciences, working on geometric and physics-inspired machine learning for biomedical applications, co-supervised by Michael Bronstein. His profile also lists a 2023 Quantitative Researcher internship at Squarepoint Capital in London.

• Quant employment verification: CONFIRMED. His LinkedIn profile (via index enrichment, not an independent primary source) lists a 2023 'Quantitative Researcher Intern' role at Squarepoint Capital, London - an actual internship, not a student program. Identity is supported by independent cross-links (IMO contestant record, Oxford CS doctoral-student page, Tong Group team page, GitHub github.com/romeopassaro). The employer is genuinely quantitative: Squarepoint Capital describes itself as a global investment manager using 'a diversified portfolio of systematic and quantitative strategies', and is covered as running a market-making unit. Caveat: the role itself rests on his self-reported profile; no independent primary source corroborates it.2023
• Represented Italy at IMO 2020 (rank 86, 86.2%) and IMO 2021 (rank 53, 91.6%, silver medal, 23 points).Jul 19, 2021
• Squarepoint Capital also operates a market-making affiliate (STG Securities), independently confirming it as a quantitative trading/market-making firm rather than a name-only 'quant'.
• Predoctoral Fellow at AITHYRA (Research Institute for Biomedical Artificial Intelligence of the Austrian Academy of Sciences), working on geometric and physics-inspired machine learning for biomedical applications, co-supervised by Michael Bronstein.
• First-author preprint 'Stochastic Few-step Models' (Feb 2026) with Zander W. Blasingame, Michael M. Bronstein and Alex Tong, placing him in Bronstein's Oxford/AITHYRA geometric-ML circle.Feb 9, 2026
• Summer 2024 ML research project 'Climate-Teleconnections' supervised by Pietro Lio (Cambridge Computer Science), presented at the 2024 Cambridge Summer Research Festival - a supervised project rather than employment.2024
• Academic timeline: BA Mathematics Cambridge 2021-2024; MMath Cambridge 2024-2025; DPhil Computer Science Oxford 2025-2028. Oxford CS independently lists him as a doctoral student.

• His arXiv coauthorship is limited: on 'Riemannian Metric Matching...' (2026) the listed authors are Bamberger, Gosztolai, Vandergheynst, Bronstein and Jones - Passaro is not among them, so that paper is not his.Jun 12, 2026
• No personal website or blog was located across GitHub, his team page, and his Oxford CS profile, so academic pages are his primary public surface.
