Notes4

• Quant employment verification: CONFIRMED. Tower Research Capital is a quantitative trading firm (high-frequency trading / electronic market-making), per its own site and Wikipedia; the subject's profile records full-time Quantitative Trader roles there (2021-03 to 2025-01, and 2025-01 to present, London). Role evidence rests on the subject's own professional profiles - LinkedIn (retrieved via a people-data index, so index-derived) and GitHub (github.com/mrgirgin, read directly, listing employer 'Tower Research Capital'). Identity is supported (LinkedIn + GitHub + IMO records, same name). No employer-side or third-party primary source independently confirms the role; the dates/titles are as stated on the self-published profiles - index-only, not independently verified.
• Employer classification: Tower Research Capital is a quantitative/HFT trading firm (not a bank or asset manager), headquartered New York with a London office; so the Quant Trader role sits squarely in quantitative finance.
• Career timeline (self-reported on LinkedIn): Software Engineer at Microsoft 2018-2020 (IoT Operating Systems team; C/C++/ARM/x86 assembly), Software Engineer II Microsoft 2020-2021, then Quantitative Trader at Tower Research Capital 2021-2025 and 2025-present (London) - i.e. moved from systems software into trading in 2021.
• Education: Bachelor's in Computational Mathematics, UCLA (2014-2018) and Master of Arts in Mathematics, UCLA (2016-2018); undergraduate research assistant in UCLA Mathematics in 2016 (automorphic functions / modular forms).
• IMO record (imo-official.org): Emre Girgin competed for Turkiye at IMO 2013 (silver, 26 points) and IMO 2014 (silver, 25 points). The IMO participant page does not itself link to the LinkedIn/GitHub profiles, so the Olympiad-to-professional-identity link is by name.
• Two professional profiles independently name Tower Research Capital (LinkedIn role history and GitHub profile) while the IMO record independently names the Olympiad identity; the three do not cross-link each other, so the identity link across them rests on the shared name rather than a mutual citation.
• GitHub (github.com/mrgirgin) shows only 2 public repositories and 1 follower, with employer listed as Tower Research Capital - a low public code footprint.
• No personal website, blog or public email is linked from the LinkedIn, GitHub or Stack Exchange profiles; the only outward links are those profiles themselves, so there is little public surface beyond the professional profiles.
