Stefano Attanasio

Quantitative researcher at Citadel (Chicago) per his LinkedIn profile, with a mathematics background from the University of Pisa / Scuola Normale Superiore and a PhD in Mathematics from New York University. Before Citadel he spent roughly six years at Credit Suisse in New York as a quantitative strategist covering credit products. He represented Italy at the 2005 International Mathematical Olympiad, winning a bronze medal. Employer/role details are index/aggregator-sourced (self-reported profile data), not primary-employer confirmed; the present employer is contested by aggregators (Citadel vs Jain Global).

Notes5

• Quant employment verification: CONFIRMED. Profile lists sustained actual quantitative-finance roles, not student programs: Quantitative Researcher at Citadel (Chicago) since 2020; Vice President, Quantitative Strategist, Global Credit Product at Credit Suisse, New York (2019-2020); Associate, Credit Suisse (2015-2018); Quantitative Summer Associate, Credit Suisse (2014). Employer classification: Citadel is a multi-strategy hedge fund/market maker (quantitative trading); Credit Suisse is a global investment bank. Identity is supported by the matching education pipeline (University of Pisa / Scuola Normale Superiore to NYU mathematics PhD) and the Italy IMO 2005 record. Caveat: role evidence is index/aggregator-sourced (self-reported LinkedIn data), not independent primary confirmation, and the present employer conflicts across aggregators (Citadel vs Jain Global).2020
• Career timeline: Citadel Quantitative Researcher (Chicago) 2020-present, preceded by Credit Suisse New York as Quantitative Strategist, Global Credit Product (VP 2019-2020, Associate 2015-2018) and a 2014 Quantitative Summer Associate internship - a roughly six-year credit-quant stint entered on completing a mathematics PhD in 2015.2020
• Education: PhD in Mathematics, New York University (2010-2015); Scuola Normale Superiore (2005-2010, final grade 70/70); University of Pisa BSc Mathematics (2005-2008) and MSc Mathematics (2008-2010) - the Pisa/Scuola Normale track is Italy's elite mathematics pipeline.2015
• Aggregator theorg lists a 'Stefano Attanasio - Quantitative Researcher at Jain Global', conflicting with the LinkedIn-indexed Citadel affiliation; Jain Global (founded by ex-Millennium CIO Bobby Jain) is a multi-manager hedge fund, so both candidate employers are quantitative-finance firms. The conflict concerns the present employer only, not the existence of quant employment.2026
• The Credit Suisse role description scopes the work as front-office quantitative strategy for corporate bonds, CDSs, CDSwaptions, tranches and other credit products (front-office pricing models) - a credit-derivatives quant mandate, not equities or market-making.2019
• Represented Italy at the 46th International Mathematical Olympiad (2005): rank 175 (66.1%), bronze medal, 17 points (P1 1, P2 7, P4 7, P6 2).Jul 2005
• No mathematics publication is attributable to this Stefano Attanasio: arXiv/ResearchGate hits under the name (e.g. 'Zero noise limits using local times' 2013, 'Local Nonuniqueness for Stochastic Transport Equations' 2023) resolve to other authors (Trevisan; Lupu/Sabot/Tarres; Modena/Schenke), so the name is shared and no paper is confirmed as his.2013
• Location: Chicago, Illinois, United States per the LinkedIn profile, while the earlier Credit Suisse roles were in New York - consistent with a relocation at the 2020 move to Citadel.2020
• PhD in Mathematics at NYU (2010-2015) sits directly between the 2008-2010 MSc in Pisa and the 2015 Credit Suisse Associate role, so the bank career began immediately on PhD completion rather than after a postdoc.2015
