Gagik Magakyan

Gagik Magakyan is a PhD student in Operations Research at MIT (since Sep 2023, advised by Asuman Ozdaglar and Pablo Parrilo) and holds a BA in Mathematics from Trinity College, University of Cambridge (2019-2022), which he attended on a full scholarship. Representing Armenia, he won medals at the International Mathematical Olympiad in 2017 (Silver), 2018 (Bronze) and 2019 (Silver), and also competed at the IOI in 2018 and 2019. His research spans optimization and machine learning: he co-authored 'General framework for online-to-nonconvex conversion' (arXiv:2411.07061) and 'Collaborative and Efficient Fine-tuning: Leveraging Task Similarity' (ICML 2026). His industry experience is ML/AI research-led — ML engineer intern at RoboK (2020), GNN research at Cambridge (2021), AI residency at X, the moonshot factory (2022-2023), and an AI internship at Microsoft (2025) — before a 2026 Quantitative Research Internship at Citadel Securities. He co-founded Kapan Math Club, which prepares students in Armenia for mathematical olympiads.
