• Quant employment verification: UNRESOLVED. The enrichment/people index (an aggregator, not primary-source) lists a Quantitative Research Intern role at Jump Trading on the profile for Halil İbrahim Güllük, but no primary source (company page, news item, personal page, or verifiable public profile text) independently confirms this internship, and targeted searches returned no corroboration. Identity of the indexed person is well supported (OpenReview 'Halil Ibrahim Gulluk', PhD EE Stanford; IMO participant id=24543 with two silvers for Türkiye 2014-2015; GitHub igulluk 'PhD in EE', Stanford CA), so the uncertainty concerns the employment claim, not the identity. Jump Trading, if the role were held, classifies as quantitative-finance employment (proprietary trading firm and market maker, per en.wikipedia.org/wiki/Jump_Trading). Index-only listing is insufficient for CONFIRMED; verification stays unresolved pending a primary source.
• Identity anchor: OpenReview profile (PhD student, EE, Stanford) and GitHub account igulluk ('PhD in EE', Stanford CA) carry matching name, role and location, and the same person appears in the IMO participant record and the Stanford profiles directory - a name+role+location cross-link, not a namesake.Aug 2026
• Official IMO participant record (participant id=24543) lists Halil İbrahim Güllük representing Türkiye with Silver Medals at IMO 2014 and IMO 2015.
• Index-listed roles (aggregator/enrichment index; not primary-source confirmed) for the LinkedIn profile: Quantitative Research Intern at Jump Trading, Summer Intern in the Clinical Imaging Group at Genentech, Deep Learning Researcher at Octai, and Summer Intern at Cezeri Yapay Zeka Robotik Teknolojileri; dates not stated and not verified. None of the other three are quantitative-finance firms.
• Education recorded across sources: Stanford University Electrical Engineering PhD (started 2021, advisor Olivier Gevaert), and Boğaziçi University Electrical Engineering (2015-2021). The index also lists Columbia University Computer Science; not confirmed by a primary source.
• Current research identity is medical AI: Stanford Gevaert Lab member working on medical imaging, vision-language models and deep learning.Aug 2026
