Semyon V. Tsynkov

Semyon V. Tsynkov is a Professor and Associate Director for CRSC at the Department of Mathematics, North Carolina State University. His research focuses on numerical methods for partial differential equations with applications to wave propagation, fluid dynamics, and inverse problems. He has made significant contributions to the development of artificial boundary conditions and difference potentials methods.

• MSc in Engineering Physics, Moscow Institute of Physics and Technology, 1989
• PhD in Computational Mathematics, Russian Academy of Sciences, 1992
• DSc in Computational Mathematics, Russian Academy of Sciences, 2004

Tsynkov's research spans multiple areas of computational mathematics and physics. His work on numerical methods for problems on unbounded domains, particularly artificial boundary conditions using difference potentials, has been influential in computational fluid dynamics and wave propagation problems. He has extensively studied non-deteriorating methods for long-time numerical simulation of large-scale 3D unsteady problems, with applications to acoustics, electromagnetism, optics, and plasma physics. His more recent work focuses on radar imaging, inverse problems in remote sensing, and active control of sound.

His publication record shows a strong focus on computational methods for wave propagation problems, particularly in the areas of SAR imaging through the Earth's ionosphere, nonlinear Helmholtz equation, and computational electromagnetics. His work often bridges theoretical numerical analysis with practical applications in physics and engineering, demonstrating both mathematical rigor and practical relevance.
