• Quant employment verification: CONFIRMED. Jeha Yang (identity supported by the linkedin.com/in/jeha-yang profile, New York quantitative researcher, matching the Stanford Statistics / Seoul National University mathematics background and the 2006-2007 Korean IMO contestant record) shows a substantive quantitative-finance employment history at Two Sigma: Quantitative Research Intern (summers 2017 and 2018), Quantitative Researcher (2019-2024), and Vice President (2024-present). Two Sigma is a New York systematic/algorithmic investment manager (SEC-registered investment adviser; quantitative, data-driven trading and investment management), so the employer is confirmed to operate in quantitative finance. The roles are actual internships and full-time roles, not student programs, insight days, camps, scholarships, or incoming offers. Caveat: the Two Sigma role/dates derive from a LinkedIn-structured index rather than a fetched primary page; the identity itself is corroborated by the IMO record and the Stanford statistics publication. No independent primary-source page naming the Two Sigma roles was located, so treat the exact titles/dates as index-only.
• Represented Republic of Korea at IMO 2006 (Silver, 23 points, rank 60) and IMO 2007 (Gold, 31 points, rank 12) as contestant 'Jeha Yang'; same name on the official Korean team rosters. This is the Olympiad identity anchor for the profile.
• Career per LinkedIn enrichment (index): Two Sigma Quantitative Research Intern (summer 2017, summer 2018), Quantitative Researcher (2019-2024), Vice President (2024-present), based in New York. Index-only; employer classification below.
• Education per LinkedIn enrichment (index): Stanford University PhD in Statistics 2014-2019 and MS in Statistics 2014-2016; Seoul National University BS in Mathematics 2008-2014. Index-only, not primary-source confirmed.
• Awards/achievements: IMO Silver medal (2006, 23 points, rank 60) and Gold medal (2007, 31 points, rank 12) for Republic of Korea.
• Two Sigma is a New York-based systematic/algorithmic investment manager (quantitative, data-driven trading and investment management), confirming the 'quantitative finance' classification of the sole employer on record.
• Co-authored 'Asymptotics of eigenstructure of sample correlation matrices for high-dimensional spiked models' (2021, Statistics) as a Stanford Statistics affiliate — a peer-reviewed signal corroborating the Stanford statistics identity.
• Publication: co-authored 'Notes on asymptotics of sample eigenstructure for spiked models' (arXiv:1810.10427, math.ST, 2018) and the related 2021 journal paper on sample correlation matrices with Morales-Jimenez and Johnstone — the Stanford statistics line in the biography.
• Appears in Stanford CS230 (Winter 2018) project listings and the STATS 325 Random Matrix Theory course repo (Spring 2016) as a Stanford student, corroborating the Stanford enrollment window.
