• Quant employment verification: CONFIRMED. Identity: the LinkedIn profile linkedin.com/in/andrii-riazanov lists Carnegie Mellon University alongside SIG and Bala-Cynwyd, PA; the CMU ACO personal site cs.cmu.edu/~ariazano redirects to andrii-riazanov.github.io, and the same person holds the IMO 2013 bronze for Ukraine (imo-official id 23280) and the May 2022 CMU PhD (dissertation CMU-CS-22-102, advisor Venkatesan Guruswami). Employment: the advisor's current UC Berkeley CV states 'Andrii Riazanov, May 2022 ... Andrii is employed at the Susquehanna International Group', a statement of actual post-PhD employment by a primary author (his PhD advisor); separately the LinkedIn profile itself (via its public directory listing and index/aggregator snapshots) records the role 'Quantitative Research Intern' at Susquehanna International Group, LLP (SIG), Bala-Cynwyd, PA, dated from June 2021. Employer classification: sig.com describes Susquehanna as 'At the Forefront of quantitative trading' - it is a global proprietary trading / options market-making and quantitative research firm, so the employer genuinely operates in quantitative finance. Caveat: the specific 'Quantitative Research Intern' job title is sourced from the LinkedIn profile and index/aggregator mirrors (zoominfo, rocketreach), which are not independent primary-source confirmation of the title; the confirmed post-PhD employment statement comes from the advisor's CV. No end date is recorded, so the exact current title/dates are not pinned down and are not inferred here.May 2022
• Identity resolved: the Andrii Riazanov of this profile is the CMU ACO PhD student whose cs.cmu.edu/~ariazano personal site now resolves to andrii-riazanov.github.io; the same CV lists both the IMO 2013 bronze (Ukraine) and CMU PhD, tying the olympiad identity and the academic identity together.Sep 2020
• PhD conferred May 2022: CMU dissertation 'Polar Codes with Near-Optimal Convergence to Channel Capacity', advisor Venkatesan Guruswami - the terminal date of the academic PhD track.May 2022
• INDEX-ONLY claim (not primary-source confirmed): a people index and web snippets record the LinkedIn profile /in/andrii-riazanov as 'Quantitative Research Intern' at Susquehanna International Group, LLP (SIG), Bala-Cynwyd, PA. This is an index/aggregator snapshot and may be stale; the role appears to be a 2021 internship.
• Susquehanna International Group (SIG) is a global market-making/proprietary trading firm headquartered in Bala Cynwyd, PA - a genuine quantitative trading employer, so a Quantitative Research Intern role there is a true quant-finance role, not a name coincidence.
• PhD at CMU (ACO program) started 2017, advisor Venkatesan Guruswami; CV dated Sep 2020 describes him as a 4th-year PhD student.Sep 2020
• Undergraduate degree is a BSc from Moscow Institute of Physics and Technology (2013-2017), Department of Control and Applied Mathematics.Sep 2020
• Research internships were in physics/applied-math labs: Los Alamos National Laboratory Theoretical Division (Jan-Mar 2017) and Skolkovo Institute of Science and Technology Center for Energy Systems (Oct 2016-Aug 2017) - not finance roles.Sep 2020
• Published theoretical CS papers with Guruswami and coauthors at STOC 2020, ICALP 2019, ISIT 2021, and earlier optimization papers (ACC 2018, ITaS 2016).Sep 2020
