• Quant employment verification: CONFIRMED. Actual quantitative-finance roles are documented: Trading Intern at Capula Investment Management LLP (2018, London; Capula is an alternative global investment manager / fixed-income hedge fund per capulaglobal.com), Quantitative Researcher at Radix Trading LLC (2019-2023; Radix is a Chicago/New York proprietary high-frequency trading firm per radixtrading.co and multiple directories), Quantitative Researcher at Citadel (2023-2025; Global Quantitative Strategies, a multi-strategy hedge fund per citadel.com), and Risk Management Intern at BCR (2016; Banca Comerciala Romana). Identity is supported by the personal blog mariusbocanu.com/about, which in his own words states he worked as a Quantitative Researcher in high-frequency trading, and by his X account @imbocanu ('Cofounder at deepdotspace'). Caveat: these employment dates/titles come from a LinkedIn-derived index/aggregator row (local index via enrich), NOT independent primary-source confirmation; the public company pages confirm the employers' quantitative nature but not his individual tenure. The current role is Co-Founder at DeepSpace (deep.space, an AI app engine), from Sep 2025, so the quant roles are past, not current. The stale upper.school profile calling him 'currently a Quantitative Researcher at an important Chicago trading firm' is outdated.
• Current focus is building DeepSpace (deep.space), an 'AI app engine' for building and deploying secure production apps, co-founded Sep 2025; his X bio reads 'Cofounder at deepdotspace - Startups, Finance, Machine Learning'. This marks a shift from quant trading to a software/AI startup.
• Employer classification: Radix Trading LLC is a Chicago-headquartered proprietary high-frequency trading firm (research-driven, machine-learning/statistical strategies) per its own site and Wikipedia; Citadel is a multi-strategy hedge fund whose Global Quantitative Strategies group runs systematic trading; Capula Investment Management LLP is an alternative global investment manager (fixed-income/hedge fund) in London; BCR is Romania's largest bank (Erste Group member).
• Represented Romania at the International Mathematical Olympiad in both 2013 (rank 131, 75.3%, silver, 24 pts) and 2015 (rank 58, 90.1%, silver, 23 pts); also earned gold medals at the Balkan Mathematical Olympiad (2013) and competed at RMM 2015.
• Personal blog mariusbocanu.com/about (published 2022-11, updated 2023-01) states he participated in the IMO in high school, moved from Romania to the US to study math at Princeton, worked as a Quantitative Researcher in high-frequency trading, and now works on ML research at NYU.
• Index/aggregator row (LinkedIn-derived, not primary confirmation) lists: Co-Founder DeepSpace (from 2025), Quantitative Researcher Citadel (2023-2025), Visiting Researcher NYU (2023), Quantitative Researcher Radix Trading (2019-2023), Trading Intern Capula (2018), Summer Researcher Princeton (2017), Risk Management Intern BCR (2016), Math Instructor/TA AwesomeMath (2014, 2016), Managing Partner RoomXcape (2015-2020).
