Irina Kalashnikova Tezaur (born c. 1984, also published as Irina Kalashnikova) is an American applied mathematician and a distinguished member of the technical staff at Sandia National Laboratories in Livermore, California.[4] During her career, she has made research contributions to several areas, including high-order discontinuous Galerkin methods, model order reduction, multiscale modeling, computational fluid dynamics of compressible flow, Earth system modeling, and concurrent multiscale coupling via the Schwarz alternating method[5].[6]


Education and career

Tezaur emigrated from Moscow, Russia to the United States with her parents, a computer scientist and a physicist, in 1992. Initially, they lived in Oak Park, Michigan,[6] later moving to nearby West Bloomfield.[3] She attended Cranbrook Kingswood Upper School, graduating in 2002.[7] Tezaur majored in mathematics and minored in actuarial science at the University of Pennsylvania, graduating in 2006 with both a bachelor's and master's degree. She went to Stanford University for continued study in computational and mathematical engineering, and completed her Ph.D. in 2011 under the supervision of Charbel Farhat.[8] Her Ph.D. dissertation is entitled "The Discontinuous Enrichment Method for Multi-Scale Transport Problems".[4]

Tezaur's graduate studies also included work as a year-round technical intern at Sandia, in its Aerosciences Department, and, when she finished her Ph.D., she became a senior member of the technical staff in Sandia's Computational Mathematics Department. She was promoted to principal member in 2015 and distinguished member in 2021.[8]

Recognition

In 2008, Tezaur was awarded the Robert J. Melosh Medal in Finite Element Analysis for her Ph.D. research involving the discontinuous enrichment method.[2] Tezaur is a 2019 recipient of the Presidential Early Career Award for Scientists and Engineers, honored "for developing new, impactful mathematical methods and computer algorithms to enable real-time analysis, control and decision-making on computationally prohibitive problems relevant to the nuclear security mission and climate modeling".[3] Tezaur has delivered invited plenary lectures at several international conferences, including the 2024 European Seminar on COmputing (ESCO), the 46th Ibero-Latin American Congress on Computational Methods in Engineering (CILAMCE 2025), and the 2026 Society for Industrial and Applied Mathematics (SIAM) Conference on the Mathematics of Planet Earth (MPE).[1]
