• Quant employment verification: CONFIRMED. Robert Dragomirescu held a Research Intern role at Diomedes Technologies from Jun 2025 to Aug 2025, per his LinkedIn experience (Jun 2025 - Aug 2025, 3 months). Diomedes Technologies is classified as a quantitative/high-frequency trading employer: its own company description and an OVHcloud customer case study describe it as a high-frequency trading firm specializing in cryptocurrency markets using advanced trading algorithms. Note the role itself, as described on LinkedIn, was a directed-reading internship on recent AI research and statistical learning theory, not documented trading-strategy work; the employer classification is quant/HFT and the internship is a real role, so classification and employment are supported, but he has no other documented quant-finance role.
• IMO record: gold medal IMO 2023 (score 46, 92.7%, rank 46) and gold medal IMO 2022 (rank 23/589, score 36); honourable mention IMO 2021 (score 10). Source is the official IMO contestant results page.
• Employer classification evidence for the only finance-adjacent role: Diomedes Technologies self-describes as 'a high-frequency trading firm with a specialization in the cryptocurrency market' and appears in an OVHcloud customer case study as 'a high-frequency trading firm focused on cryptocurrency markets' using advanced trading algorithms; this supports treating it as a quant/HFT employer rather than a generic tech company.
• Trajectory from Romanian Olympiad to Stanford: BS in Mathematics at Stanford University 2023-2027; high school was the International Computer High School of Bucharest 2019-2023, so he left Romania for Stanford the same year he finished high school.
• 3rd place at the 2024 Putnam Competition as part of Stanford's team (best result in Stanford history, tied), plus a personal honorable mention in the top 100.
• No quant-finance role beyond the 2025 Diomedes internship was found: searches for his name with 'quant', 'hedge fund', 'market making', and GitHub returned only his LinkedIn profile and the Diomedes internship; there is no evidence of trading, market-making, or systematic-trading employment at banks, asset managers, or energy/crypto trading firms.
• Silver medal at the third Al-Khorezmi International Mathematical Olympiad (AKHIMO) in Uzbekistan, June 2025; one of the few American medalists.
• Co-authored a 2024 SURIM (Stanford Undergraduate Research Institute in Mathematics) report, 'Markov Chains, Martingales, and Random Walks on Electrical Networks', with Ally Bush, Jack Hlavka and Alice Zhu; the report is listed under Probability and Statistics.
• Mentor/teacher on Upper.School's HiPerMath program since 2020, progressively moving from grading and problem-setting to teaching and advanced mentorship.
• Stanford Profiles lists him as a Mathematics and Institute for Computational and Mathematical Engineering (ICME) undergraduate.
• Placed in the top 200 in the 2025 Putnam Competition (Stanford team 4th of 487 teams).
• Honorable mention (top 100) in the 2023 Putnam Competition.
