Rogério Aristida Guimarães Junior

Rogério Aristida Guimarães Junior is a Brazilian computer scientist and PhD candidate in Computation and Neural Systems at Caltech's Computational Vision Laboratory, researching how animals (mice) learn to navigate and reproducing those learning algorithms in AI models. He earned dual BS degrees from MIT in Computer Science and Engineering and in Linguistics and Philosophy (2017-2021), and represented Brazil at the International Olympiad in Informatics, winning Silver in 2016 and Bronze in 2017. His industry experience spans a Summer 2020 Investment Engineering Internship at Bridgewater Associates (a macro hedge fund), a 2021 data science internship at ZEISS Medical Technology (producing a patent), a 2019 software engineering internship at Pegasystems, and a current Google student-researcher role.

• Quant employment verification: CONFIRMED. Bridgewater Associates is a macro hedge fund / investment management firm (bridgewater.com); his own CV lists 'Investment Engineering Intern' at Bridgewater Associates, Westport CT, Jun 2020 - Aug 2020, where he 'analyzed select case studies to develop hypotheses to explain and predict the business cycle' and 'built a fully automated sample bond trading system' - an actual summer internship in a quantitative/macro investment role, matching the LinkedIn index entry. Identity is supported by the CV hosted on his personal site, cross-linked from his LinkedIn, and by the MIT SuperUROP page listing his MIT credentials. No other quant-finance employer (bank, asset manager, energy/crypto trading) appears in his verified timeline: Pegasystems (software), Zeiss (medical imaging), Google (research), Caltech (academic research) are not quantitative-finance firms. Current roles (Caltech graduate researcher 2021-, Google student researcher 2025-) are research, not trading.Aug 2020
• Bridgewater role is titled 'Investment Engineering Intern' on his CV, i.e. a summer internship (Jun-Aug 2020), not a full-time 'Investment Engineer' position as the index lead implied - a distinction the index-only role entry obscures.Aug 2020
• Named inventor on Patent US 2023/0196572 A1 (OCT image segmentation using Transformer processing of 1D A-scans), resulting from his 2021 Zeiss Medical Technology data science internship.Jun 2023
• 2021 Caltech Tianqiao and Chrissy Chen Graduate Fellow - a first-year neuroscience fellowship - placing him in Caltech's CNS PhD program at entry in 2021.Sep 2021
• IOI medals for Brazil: Silver 2016 (Russia) and Bronze 2017 (Iran), corroborated independently by the official IOI statistics database (stats.ioinformatics.org/people/5861) and his CV.Aug 2017
• MIT SuperUROP scholar 2019-2020, 'Tang Family FinTech Undergraduate Research and Innovation Scholar', research 'A Collaborative Filtering Approach to Strategy Recommendation' supervised by Mardavij Roozbehani - a fintech-flavored research project, but an academic research program, not employment.Sep 2019
• MIT Burchard Scholar 2019/2020 (humanities) alongside dual MIT BS degrees in Computer Science and Engineering and in Linguistics and Philosophy, and a prior undergraduate research stint at MIT LIDS from Jan 2019.Jan 2020
