Tatyana Sizyuk

Computational Scientist

Tatyana Sizyuk specializes in multi-physics simulations, code developments, hybrid methods for modeling various plasma physics systems, simulations of fusion reactors, and optimization methods for high-performance computing.


Tatyana Sizyuk performs development of models and research in the areas of plasma/material interactions in fusion reactors, laser and discharge produce plasmas for industrial and biomedical applications, optimization of multi-physics packages for high performance computing. She developed hybrid models for Monte Carlo and continuum simulations of plasma/particle interactions with materials, particle transport, materials mixing, and fuel retention in plasma facing materials in fusion reactors. She is one of the key developers of ITMC-DYN package that combines and integrate all collisional and thermal processes in one package. The developed package with many capabilities is used for the simulation of real lab and fusion reactor experiments. She is the PI of the project for modeling the largest fusion device in USA, i.e., DIII-D Tokamak reactor experiments at General Atomics, San Diego, Ca.

Prior to joining Argonne in 2021, Tatyana was the Associate Director of the renowned center for materials under extreme environments (CMUXE) and worked as a Research Scientist and an Assistant Professor at Purdue University (from 2007 to 2021). Her areas of interests and research included optimized Monte Carlo methods for particles/radiation interaction with matter, hydrodynamics, plasma and atomic physics; code development, validation, optimization for parallel calculations, and benchmarking; numerical simulations of plasma/material interactions in lithography and fusion devices, radiation damage in materials, laser and discharge produced plasmas for photon sources. She is also one of the main developers of the HEIGHTS comprehensive computer package which is unique worldwide with multi-dimensional multi-scale physics for integrated modeling of plasma physics devices in various areas including Federal Government (DOE, HEDP, NNSA, etc.), industrial, and biomedical applications. These activities included numerous collaborations with national and international semiconductor companies such as INTEL, SEMATECH, KLA, Samsung, and ASML/Cymer. Prior to moving to Purdue University, Tatyana worked as a Research Scientist at ANL from 2004 to 2007.

Tatyana has given numerous invited talks and chaired sessions and committees in international conferences. She has over 60 journal publications in highly ranked journals including Physics of Plasmas, J. Applied Physics, Nuclear Fusion, J. Nuclear Materials, Scientific Reports, etc.

Tatyana is a member of several professional societies including SPIE (Fellow Member), IEEE (Senior Member), Optica (former OSA) (Member), APS (Member), and ANS (Member).
