Notes7

• Quant employment verification: CONFIRMED. Julien Samaha's profile shows sustained front-office quantitative finance employment: Quantitative Trader at Barclays Investment Bank, Executive Director (commodity quant) at Morgan Stanley, Head of Commodity Quants (Executive Director) at UBS Investment Bank, and Tech Lead - Commodities at Citadel LLC, plus quantitative analyst roles at Credit Lyonnais/Rouse. These are actual roles at firms that genuinely operate in quantitative finance (two investment banks' commodity quant desks and a major hedge fund/market maker); none are student programs. Identity is supported: the IMO 1995 record (France, bronze) matches the LinkedIn profile's stated Olympiad bronze and Lycee Louis-Le-Grand/ENSAE education, and Companies House independently lists Julien Henri Samaha as director of Quantor Associates Limited. Caveat: the specific role titles and dates are index-derived (LinkedIn enrichment), so they are labeled index-only rather than independent primary-source confirmation; the only independently primary-sourced role is the Quantor Associates directorship.
