Tiago Oliveira Marques

Tiago Oliveira Marques is a Portuguese mathematics and computer-science talent, currently an undergraduate researcher in the MIT Department of Mathematics. He represented Portugal at the International Olympiad in Informatics (IOI) in 2021 (score 191, rank 192/351) and 2022 (Honourable Mention, 126.50/600, rank 200/349), and won gold medals at the Ibero-American Informatics contest (CIIC) in 2021 and 2022. He is also an International Mathematical Olympiad medalist (silver 2021, bronze 2022) and a multiple-time national mathematics olympiad winner. He attended Colegio Internato Claret in Vila Nova de Gaia before MIT, and held a theoretical-computer-science research fellowship at ETH Zurich.

Notes5

• Cross-linked identity: the CPHF.io IOI profile (contestant 7565) links the Codeforces account Tiago_Marques, whose registered real name is 'Tiago Oliveira Marques' from MIT - confirming the IOI contestant and the MIT student are the same person.
• Reached both the IOI (Informatics) and IMO (Mathematics) international olympiads for Portugal in the same period - a rare dual-threat in informatics and olympiad mathematics.
• Selected for Portugal's IOI 2022 team (with Jorge Costa, Tomas Faria, Tiago Sousa) via the ONI 2022 national selection test; team led by Prof. Pedro Ribeiro and Duarte Nobrega.
• Won the Portuguese National Mathematics Olympiad seven times, per national press.
• Studied at Colegio Internato Claret in Vila Nova de Gaia, a school that produced several of Portugal's IOI team members.
