Tianze Jiang
Tianze Jiang is a Ph.D. candidate in Princeton University's Department of Operations Research and Financial Engineering (ORFE), advised by Prof. Boris Hanin and supported by the Francis Robbins Upton Fellowship. He earned a B.S. from MIT in 2024 with a double major in Mathematics and Computer Science (GPA 5.0/5.0) and is completing an M.A. at Princeton (2026). He represented the United States at the 61st International Mathematical Olympiad (2020), winning a silver medal, and was a USAMO 2020 winner (5th nationwide). His research applies mathematical physics, statistics and probability to deep learning, including scaling laws and training dynamics. In summer 2024 he was a Quantitative Research Intern at Citadel Securities (FICC and Systematic Equities), building market impact accounting models of high-frequency US equities trades, and in 2026 he is a research scientist intern at Meta AI (FAIR).
- Quant employment verification: CONFIRMED. Tianze Jiang worked as a Quantitative Research Intern at Citadel Securities from June to August 2024 in Miami, FL, on FICC and Systematic Equities, building market impact accounting models of high-frequency US equities trades (his own CV, hosted on his personal site). Citadel Securities is a market maker / electronic trading firm, so the employer is unambiguously quantitative finance. Identity is supported: the CV sits on his verified personal site (petyrrrrr.github.io) and its name, MIT degree and Princeton PhD match the LinkedIn and ORFE pages.Aug 2024
- Current position is a Ph.D. candidate in Princeton's ORFE department (2024-present), advised by Boris Hanin and funded by the Francis Robbins Upton Fellowship, per the department's own people page.2024
- Summer 2026 research scientist internship at Meta AI (FAIR), June-December 2026, in AI alignment, theory and optimization; listed on his personal site and CV.Jun 2026
- Research spans deep learning theory, scaling laws of deep networks, high-dimensional statistics and average-case complexity; publications at NeurIPS 2023, COLT 2023-2024, JMLR and ICML 2026.2026
- Earned a B.S. from MIT in 2024, double majoring in Mathematics and Computer Science with a 5.0/5.0 GPA, per his CV.2024
- Represented the United States at the 61st International Mathematical Olympiad (IMO 2020) and won a silver medal; the MAA's official team release names the US team.Sep 2020
- The Citadel Securities role is the only quant-finance employment the primary sources establish; it is described as an internship, not a full-time role.
- Won the 2020 USA Mathematical Olympiad (USAMO), placing 5th nationwide.2020
- A 'Quantitative Researcher' role at TongDeng Fund (May-Aug 2021) appears only in the LinkedIn/index lead and is NOT listed on his own CV, so it is index-only and unconfirmed as an actual role or internship; treat as uncertain, not established employment.
- Scored N1 (top 15 overall) on the 2021 William Lowell Putnam Mathematical Competition.2021
