Binwei Yan

Binwei Yan is a quantitative researcher. She represented the People's Republic of China at IMO 2020 (silver medal), then studied at MIT, where she double-majored in Mathematics and EECS and won the 2022 Elizabeth Lowell Putnam Prize as the top-scoring woman (16th overall). LinkedIn-indexed data lists her as a Quantitative Researcher at Citadel Securities (Miami) since 2024, after a summer 2023 Quantitative Researcher internship there, with prior MIT research roles in computational biology and machine learning. Her current employment rests on index-only data, not independent primary-source confirmation.

• Quant employment verification - CONFIRMED. LinkedIn-indexed data (index-only, not independent primary confirmation) lists a current Quantitative Researcher role at Citadel Securities (Miami) from 2024 and a summer 2023 Quantitative Researcher internship at Citadel Securities (Chicago). Citadel Securities is a genuine quantitative market maker (its own site: 'technology-driven, next-generation global market maker ... quantitative research'), so both roles are actual quantitative-finance work, not student programs. Identity is supported independently of the index by MIT primary sources tying the same name to the China IMO 2020 silver medalist and 2022 Putnam top-scoring woman. Because the roles themselves rest on index-only data, the employment is CONFIRMED-with-caveat: strong, verified-employer, real-role evidence, but not yet cross-checked against a non-index primary source.2024
• Current role per LinkedIn-indexed data: Quantitative Researcher at Citadel Securities in Miami, Florida, from 2024 (index-only; not independently primary-confirmed).2024
• Won the 2022 Elizabeth Lowell Putnam Prize as the top-scoring woman on the 83rd William Lowell Putnam Mathematical Competition, finishing 16th overall with a $1,000 award - the sixth MIT student and fourth in a row to take the honor.Mar 3, 2023
• Won the 2022 Elizabeth Lowell Putnam Prize as the top-scoring woman on the 83rd Putnam (16th overall, $1,000); the sixth MIT student and fourth in a row to take the honor, and an MIT math page independently describes her as an Olympiad veteran with the IMO silver medal and Mirzakhani Award - this page links the Olympiad identity and the MIT student into one person.Mar 3, 2023
• Official IMO record: Binwei Yan, People's Republic of China, IMO 2020 silver medal, rank 59, 29 points (contestant id 30039) - independent primary confirmation that the Olympiad identity is real and matches the name.2020
• Summer 2023 Quantitative Researcher Intern at Citadel Securities (Chicago) per LinkedIn-indexed data - a real internship role, index-only.2023
• MIT research roles before Citadel: Research Assistant using biology for portfolio construction with Prof. Manolis Kellis and Prof. Andrew Lo (2023-2024); undergraduate research in Samuel Madden's lab (ML for database preprocessing, 2022-2023); Kellis lab graph-neural-network cell-cell communication (2022-2023); Bonnie Berger lab ML for antibody interaction prediction (2021-2022) - index-only.2021
• MIT research history before Citadel (index-only): Research Assistant applying biology to portfolio construction with Prof. Manolis Kellis and Prof. Andrew Lo (2023-2024); undergraduate ML/data work in Samuel Madden's lab; graph-neural-network cell-cell communication in Kellis's lab; ML for antibody-interaction prediction in Bonnie Berger's lab (2021-2022). The Kellis/Lo portfolio-construction stint is the closest pre-Citadel quantitative-finance-adjacent work.2021
• Education: MIT Bachelor and Master's in Mathematics and Computer Science (2021-2024); prior year at Tsinghua University studying Computer Science (2020-2021) - index-only.2020
• Education (index-only): MIT Bachelor and Master's in Mathematics and Computer Science (2021-2024), double majoring in Math and EECS per MIT pages; one prior year studying Computer Science at Tsinghua University (2020-2021) before transferring to MIT.2020
• Namesake caution: search returns other distinct 'Binwei Yan' people - an NLP/finance-LLM researcher (ACL/arXiv author, China Agricultural University) and a New York financial advisor - whose publications and titles are NOT this subject's; only facts cross-linked to MIT, IMO 2020 China, or Putnam are attributed here.2025
• Identified as the 2022 top-scoring woman (16th overall) in MIT Technology Review's coverage of MIT sweeping the Putnam top five; photo caption names her among the 2022 Putnam honorees.Apr 25, 2023
