Aymen Echarghaoui

Aymen Echarghaoui is a mathematics and statistics researcher from Morocco. He represented Morocco at the 2018 International Mathematical Olympiad (honourable mention, 12 points). He studied at Lycée Louis-le-Grand in Paris and earned a Master of Engineering (MEng) in Applied Mathematics & Computer Science at École Polytechnique. He has pursued a PhD in Statistics at Stanford University (admitted Autumn 2024) and is listed as a PhD Candidate in the Decision, Risk, and Operations Division at Columbia Business School. His research spans high-dimensional statistics/sparse regression (work with Robert Tibshirani) and the theory of evolutionary/genetic algorithms (work with Benjamin Doerr). He has held research internships at Squarepoint Capital and Huawei's Paris Research Center.

• CONFIRMED. Squarepoint Capital is a global quantitative investment manager (systematic/algorithmic trading hedge fund); its own site and public profiles describe quantitative investment strategies. The LinkedIn profile for Aymen Echarghaoui lists Quantitative Research Intern at Squarepoint Capital twice: London, England (2023) and Paris, Île-de-France (2024-, listed current). This is actual employment/internship, not a student program, insight day, camp or scholarship. Identity is corroborated across independent records (Stanford Statistics profile, Columbia Business School DR&O profile, arXiv author pages, IMO/IMC contest records, École Polytechnique). Note: the Squarepoint roles and dates are asserted by the LinkedIn index/enrichment and are not independently re-verified on Squarepoint's own pages, so those specific dates remain index-only.2026

• Other employers identified do not qualify as quantitative finance: Huawei Paris Research Center (research internship on deep learning for network traffic classification) is a technology/telecom R&D employer, and Lycée Louis-le-Grand (oral examiner in Mathematics) is an educational institution. Only Squarepoint Capital among the leads is a quantitative finance employer.2026
• Publicly listed Stanford academic email [contact omitted] on the official Stanford Profiles page.2026
• Squarepoint Capital is a private quantitative investment firm that runs systematic trading strategies across asset classes; its engineering teams build the technology supporting those quantitative investment strategies, confirming it operates in quantitative finance rather than merely having a 'quant'-sounding name.2026
• Confirming the Olympiad identity: the imo-official.org contestant record for Aymen Echarghaoui (Morocco, 2018) shows an Honourable Mention with 12 points, rank 338. This is the person named in the brief.2018
• Listed as a PhD student in Statistics at Stanford University (admitted Autumn 2024) and as a PhD Candidate in the Decision, Risk, and Operations Division at Columbia Business School; both are academic research affiliations, and the two entries together suggest a doctoral path spanning both institutions.2026
• Two separate Squarepoint Capital Quantitative Research Intern stints are listed (London 2023, Paris 2024-), indicating a return internship at the same firm in different offices; dates are index-asserted and not independently confirmed on Squarepoint pages.2026
• Co-authored 'Univariate-Guided Interaction Modeling' with Robert Tibshirani (arXiv 2512.14413), proposing sparse regression with pairwise interactions and proving support recovery; it generalizes the UniLasso methodology, placing him in high-dimensional statistics.Dec 16, 2025
• Co-authored 'Lasting Diversity and Superior Runtime Guarantees for the (mu+1) Genetic Algorithm' with Benjamin Doerr, Mohammed Jamal and Martin S. Krejca (arXiv 2302.12570), with a hot-off-the-press track summary at GECCO 2024; research in the theory of evolutionary algorithms.Feb 24, 2023
• Research Scientist Intern at Huawei Paris Research Center (2022) working on Generalised Open World Class Discovery for network traffic data using deep learning; a technology-sector research internship that further supports the machine-learning side of his profile.2022
• Won a gold medal at the International Mathematics Competition (IMC) 2021 while a student at École Polytechnique, reported alongside fellow Moroccan Issam Tauil; the report notes they were in third and second year at École Polytechnique. A competition result, distinct from employment.Sep 7, 2021
