Mehdi Khayeche

Tunisian olympiad mathematician (IMO 2011/2012/2013; 2012 Silver, 2013 Honourable Mention; PAMO 2012 3rd; EGMO 2015 Tunisia Deputy Leader). Index records associate the name with a Toronto-based TD fraud/risk career and a University of Waterloo mathematics degree; these are index-only and not primary-source confirmed, and no quantitative trading or investing employment is evidenced.

• Quant employment verification: NOT CONFIRMED. The only employment evidence located is TD Securities 'Risk Analyst' (2020-2022) and TD 'Senior Fraud Strategist' (2022-present). Risk analysis and fraud strategy are risk/compliance roles, not quantitative investment, trading, market-making or systematic/algorithmic trading. TD Securities is classified in the company index as Investment Banking (a bank capital-markets arm), not a quant fund or prop trading firm. No hedge-fund, market-making, energy- or crypto-trading employer was found, and no primary source corroborates the identity link between the Olympiad subject and the TD roles, so the quant-employment claim is not established.Sep 17, 2026
• Identity caveat: the Olympiad record ('Mohamed Mehdi Khayeche', Tunisia) and the Toronto TD professional ('Mehdi Khayeche', University of Waterloo) share a name and math background but no located source directly links them; the Waterloo-mathematics + online Olympiad-solver trail is circumstantial, so treat the education/employment as index-derived pending a primary corroboration.Sep 17, 2026
• LinkedIn/index records (index-only, not primary-source confirmed) list 'Mehdi Khayeche' as Senior Fraud Strategist at TD in Toronto, Ontario, Canada, since 2022, and previously Risk Analyst at TD Securities (Toronto) 2020-2022, with a Bachelor's degree in Mathematics from the University of Waterloo.Sep 17, 2026
