Tudor Darius Cardaș

Tudor Darius Cardaș is a Romanian mathematician and operations-research student. He represented Romania at the International Mathematical Olympiad in 2019 in Bath, winning a bronze medal (22 points, rank 168), after earlier winning gold at the Balkan Mathematical Olympiad and Prize I at Romania's National Mathematical Olympiad while a student at Colegiul Național 'August Treboniu Laurian' in Botoșani. He then read a double degree in Mathematics and Economics at École Polytechnique (2021-2024) and is now completing a Master's in Operations Research at Université Grenoble Alpes, specializing in ORCO (Operations Research and Combinatorial Optimization).

• Won bronze at IMO 2019 in Bath, UK, scoring 22 points (rank 168, 73.1%): problem-by-problem 7,6,0,7,2,0 (P1-P6).Jul 2019
• Won bronze for Romania at IMO 2019 in Bath, scoring 22 points (rank 168, 73.1%); problem-by-problem 7,6,0,7,2,0. Teammates that year: Edis Memiș (gold), Sergiu-Ionuț Novac and Sebastian Mihai Șimon (silver), Andrei Theodore Mărginean (bronze, same 22 points), Nguyen Tran Bach (bronze) - Romania placed 17th with 155 total points.Jul 2019
• LinkedIn headline self-describes as a '2 time IMO medalist', implying a second IMO medal besides 2019 bronze.2026
• LinkedIn headline reads '2 time IMO medalist', implying a second IMO medal besides the 2019 bronze - consistent with Romania's practice of returning strong olympians to the team in a later year.2026
• As a Laurian ninth-grader (2017-18) he self-described as math-informatics and was coached by teacher Liliana Tomita; he took Prize I at the national math olympiad and a Balkan MO gold, then secured a place on Romania's senior team for the 2018 Tuymaada International Multidisciplinary Olympiad in Yakutsk - a trajectory that culminated in his 2019 IMO selection.Apr 7, 2018
• After École Polytechnique he moved into applied math research: a 2024 bachelor thesis on biased random walks, then a 2025 G-SCOP internship on online algorithms with predictions and the risk-measurement sensitivity of competitive analysis - a clear pivot from pure olympiad math toward operations research and optimization.2025
• Studied at Colegiul Național 'August Treboniu Laurian' Botoșani (2017-2021), math-informatics, coordinated by teacher Liliana Tomita; won Prize I at the Romanian National Math Olympiad and earned gold at the Balkan MO.Apr 7, 2018
• In 2018 secured a place on Romania's senior team for the Tuymaada International Multidisciplinary Olympiad in Yakutsk, a step that prefigured his 2019 IMO selection.Apr 7, 2018
• Botoșani city council voted him a 2,000-lei merit award in August 2020 for his olympiad results, showing sustained local-recognition of his trajectory through the COVID-disrupted school year.Aug 28, 2020
• Maintains a Codeforces account as 'Tudor_Cardas' (Specialist) listing Botoșani, Romania - a competitive-programming footprint complementing his olympiad record.2026
• Served as a board member of ConsultX at École Polytechnique (2022-2023), a student consulting organization - an extracurricular leadership signal distinct from his pure-math track.2023
