Igor Medvedev

Igor Medvedev is a Mathematics PhD student at Princeton University, advised by Mihalis Dafermos, working in mathematical general relativity and the analysis of PDEs. He completed a BA in Mathematics at Princeton (2018-2022) and a one-year MAst (Part III) in Mathematics at Trinity College, Cambridge (2022-2023). As a high-school student at Matematicka gimnazija in Belgrade he represented Serbia at the International Mathematical Olympiad in 2016, 2017 and 2018, winning Bronze, Bronze and Silver medals respectively. He held quantitative/trading internships at Radix Trading LLC (Quantitative Research Intern, 2021) and Five Rings Capital, LLC (Trading Intern, 2020).

• Quant employment verification: CONFIRMED. Two actual internships: Quantitative Research Intern at Radix Trading LLC (Chicago, 2021) and Trading Intern at Five Rings Capital, LLC (New York, 2020). Employer classification: Radix Trading is a quantitative/algorithmic trading research firm (radixtrading.co describes itself as 'a research firm, powered by technology and monetized through trading', using 'machine learning and statistical methodologies', offices Chicago/New York/Amsterdam) - a genuine quant trading firm. Five Rings Capital is a New York proprietary trading firm; the role title 'Trading Intern' is a trading role. Identity is supported: the LinkedIn profile carries the Princeton math PhD signal and the Serbia IMO contestant (same name, same age cohort). Index-only note: the specific 2021-06..2021-08 and 2020-06..2020-08 month ranges come from the caller's lead/index and are not independently confirmed by a primary page read this run; the years 2020 and 2021 are shown on the LinkedIn-backed enrichment.Sep 17, 2026
• IMO: Igor Medvedev (Serbia) - Bronze 2016 (106th? score 18), Bronze 2017 (score 17), Silver 2018 (score 28); medal years 2016/2017/2018 match the task's olympiad identity.Jul 2018
• Currently a Mathematics PhD student at Princeton University (Fine Hall 904, [contact omitted]); the department directory lists him among graduate students and as graduate student representative on the Fine Hall committee.
• Awarded Silver at IMO 2018 with a score of 28 (85.5%), ranking 87th - the strongest of his three IMO appearances; the 2016 and 2017 outings were Bronze.Jul 2018
• Advised by Mihalis Dafermos at Princeton (listed among Dafermos's PhD students); his area is mathematical general relativity / analysis of PDEs.
• Read a one-year Cambridge MAst (Part III) in Mathematics 2022-2023; his LinkedIn summary at that time states he would begin a math PhD at Princeton the following year.Jun 2023
• Attended Matematicka gimnazija (Belgrade) high school 2012-2018, the specialist mathematics gymnasium whose students populate Serbia's IMO teams.
• Undergraduate BA in Mathematics at Princeton University 2018-2022, starting the same year he finished high school and his final IMO.
• Presented/attended the ICERM topical workshop 'EBH' (2026) at Brown University, listed alongside Princeton mathematicians - active in the general-relativity analysis community.2026
• Note on namesakes: multiple distinct 'Igor Medvedev' profiles exist (oceanographer at Shirshov Institute, orcid 0000-0003-0748-0062; a .NET developer; a 1931-2015 painter). None match the Princeton math PhD, so identity resolution rests on the LinkedIn URL plus the Princeton department page.
• Credited as the photographer for a Mihalis Dafermos photo used in the AMS Notices 2026 Prizes and Awards piece - a small marker of proximity to Dafermos's research circle.Apr 2026
• Co-authored/contributed to Princeton's PUMA (PUMaC) 2021 power-solutions document, thanked for 'incredible support and feedback' on contest problem solutions.2021
