Alexandros Mousatov

Theoretical physicist and quantitative researcher. IMO bronze medalist for Greece (2011, 2012); Yale BS Physics / MS Mathematics; Stanford PhD in Physics (2021, research on black hole information and operator growth). Listed on LinkedIn as a Quantitative Researcher at Aquatic Capital Management (Chicago) since October 2023 (index-only).

Notes7

• Quant employment verification: UNRESOLVED. The role is an actual quantitative-finance position (Aquatic Capital Management, Quantitative Researcher, Chicago, from 2023-10) as listed on LinkedIn, and the identity is supported (Yale BS Physics/MS Math -> Stanford Physics PhD 2021 -> Chicago quant, education timeline matches the 2012 Greek olympiad student). Employer classification is CONFIRMED as genuinely quantitative: Aquatic Capital Management is a systematic/quantitative-research firm founded by Jonathan Graham, former Citadel Partner who ran Citadel's Global Quantitative Strategies business. The employment claim itself remains UNRESOLVED because the only evidence is the LinkedIn/index listing — index-only, not independent primary-source confirmation; no company, press or filing document states the role. No past internships or other quant roles were found.Oct 1, 2023
• Quant employment verification (see also note of the same title): the only evidence of the Aquatic Capital Management role is the LinkedIn/index listing (Chicago, Quantitative Researcher, from 2023-10); no independent primary-source confirmation of the role was found. Per task rule, this is index-only and is not treated as independent primary-source confirmation.Oct 1, 2023
• Aquatic Capital Management is a quant/quantitative research firm focused on systematic trading: founded by Jonathan Graham (a former Citadel Partner and head of its Global Quantitative Strategies business), described as a research-and-development company for exceptional technical talent and hiring Quantitative Researchers — this is a genuine quantitative-finance employer, not merely a name containing 'quant'.Jan 1, 2025
• Identity resolution: the LinkedIn 'Alexandros Mousatov' (Chicago, PhD Stanford Physics, BS/MS Yale) is the same person as the Greek IMO 2011 and 2012 contestant — the education timeline (Yale from ~2012, Stanford PhD to 2021) matches the 2012 news of a 17-year-old Greek student winning a Yale scholarship, and the physics/mathematics background matches the olympiad profile.May 14, 2012
• Stanford PhD in Physics conferred 2021; dissertation defense titled 'String Spreading and Black Holes' on 2021-05-20, research advisor Eva Silverstein; committee included Patrick Hayden and Douglas Stanford.May 20, 2021
• IMO participation: bronze medal for Greece at IMO 2011 (16 points, rank 253) and IMO 2012 (17 points, rank 182). Olympiad context only, not employment evidence.Jul 1, 2012
