Mehdi Ouaki

Mehdi Ouaki (full name Mohamed Mehdi Ouaki) is a quantitative researcher at Two Sigma in New York. He represented Morocco at the 2012 International Mathematical Olympiad, earning a bronze medal, then completed an M.Sc. in mathematics at Ecole Polytechnique (2014-2017) and a PhD in Statistics at UC Berkeley (2017-2022) under Steven Evans and Fraydoun Rezakhanlou, with a dissertation on Markov processes and variational problems. He received UC Berkeley's Bernard Friedman Memorial Prize in Applied Mathematics for 2021-22. His quantitative-finance roles include Two Sigma (corroborated by Berkeley's own alumni-employment listing) and, per LinkedIn index data only, Citadel Securities (2020) and Squarepoint Capital (2017).

• Quant employment verification: CONFIRMED. Mehdi Ouaki holds an actual quantitative-research role at Two Sigma: UC Berkeley Statistics' own department profile lists 'Quantitative Researcher at Two Sigma' under his Alumni Employment History, an institutional page independent of the LinkedIn index. Two Sigma (twosigma.com) is a quantitative hedge fund/asset manager. His LinkedIn enrichment (index-only) additionally lists Quantitative Researcher at Citadel Securities (2020, Chicago) and Squarepoint Capital (2017, London); both are genuine quantitative trading/market-making firms, but those two roles rest on the index alone and are not independently corroborated. Identity is supported: same person as 'Mohamed Mehdi Ouaki', Morocco's IMO 2012 contestant (rank 182, bronze), who became a Berkeley Statistics PhD (2022) and whose dissertation/email ([contact omitted]) match. No evidence of student-only programs; the Two Sigma role is substantive.
