Suchan Vivatsethachai is a quantitative researcher at QuantCo, a data-science and AI software firm. He represented Thailand at the International Mathematical Olympiad in 2013, 2014 and 2015, and studied at MIT, earning an SB in Mathematics (with a minor in Statistics and Data Science) in 2020 and an MEng in Electrical Engineering and Computer Science in 2021. His work history includes a Quantitative Analyst Internship at Tech Square Trading (a quantitative equity investment firm) in summer 2017 and a Software Engineer Internship at Google in summer 2018. At MIT he was a 2018-2019 SuperUROP scholar in David Sontag's clinical machine learning group.

• Quant employment verification: CONFIRMED. A real internship - 'Quantitative Analyst Intern' at Tech Square Trading, Jun-Aug 2017 - is recorded on his LinkedIn work history, and the identity is supported (same profile ties the MIT EECS/QuantCo researcher to the Thai IMO contestant). Tech Square Trading was a genuine quantitative equity investment firm (Kendall Square, Cambridge, MA), confirmed by Preqin and RocketReach, not merely a name containing 'quant'. His other listed roles (Google SWE intern; current QuantCo researcher) are not quant-trading roles; QuantCo is a data-science software firm.
• Index/aggregator listings (Wiza, SignalHire, Datanyze) record the role 'Quantitative Researcher at QuantCo'; QuantCo is a data-science/AI software firm serving enterprises (insurance, pricing, claims, precision medicine), not a trading firm, so this role is not quant-trading employment.Sep 17, 2026
• In his own words (IMO 2023 sponsor booklet) he completed bachelor's and master's degrees in computer science and mathematics at MIT, is passionate about combinatorics, probability and statistics, and at QuantCo builds machine learning models, optimizes solutions and programs high-performance code.Jul 1, 2023
• Completed an SB in Mathematics (Course XVIII) with a minor in Statistics and Data Science at MIT in February 2020, then an MEng in EECS in 2021 with the thesis 'Robustness of Consistent Loss Functions for Multinomial Outcome Models'.
• Employed at QuantCo and represented the company at the IMO 2023 sponsors' booth in Chiba, Japan alongside two colleagues.Jul 1, 2023
• Suchan Vivatsethachai represented Thailand at the International Mathematical Olympiad in 2013, 2014 and 2015; IMO 2015 team page lists him at 19 points (96.9%).
• Software Engineer Intern at Google, Sunnyvale CA, Jun-Aug 2018 (per LinkedIn work history).
• 2018-2019 SuperUROP scholar in MIT EECS under David Sontag, researching transfer learning across hospitals via latent patient-hospital sub-mechanisms; listed among Sontag clinical ML lab undergraduates.
• Putnam Competition: received an honorable mention in 2015 and is listed among MIT winners in the 2016 announcement.
• Co-authored code in MIT clinicalml 'parkinsons-disease-progression-modeling' (latent variable modeling and subtyping) as a class project in Sontag's group.
