Viktor Fedun attended secondary school in Kiev, Ukraine, from 1984-89, earning a gold medal distinction. In 1994, he completed a MSci in Physics from National Taras Shevchenko University, Physics faculty, Kiev, Ukraine with the top grade of an 'excellent' classification. In 1998, Viktor went on to earn a PhD in Heliophysics and Physics of the Solar System from the same institution. Viktor's PhD thesis was titled 'Nonlinear parametric wave interactions in the near Earth plasma'.
Whilst completing his PhD, Viktor Fedun worked as a Research Officer at the National Taras Shevchenko University. In 1998, he went on to become a research fellow, followed by a senior research fellow. From 2000-04, Viktor also worked as Chief Computing Officer at the Scientific and Production Center "Viateh" in Kiev, Ukraine.
Viktor joined the University of Sheffield in 2005 with a STFC Rolling Grant PDRA at the School of Mathematics and Statistics (SoMaS). In 2012, Viktor became a lecturer in Control and Systems Engineering, in the department of Automatic Control and Systems Engineering. He became a senior lecturer in 2018.
- Research interests
-
My research is primarily concerned with the mathematical modelling of physics of
- solar/space plasmas;
- sun-solar wind;
- solar-terrestrial systems.
The study of processes occurring in such systems is crucially important for understanding the Sun, predicting Space Weather and understanding the dynamics of laboratory and technological plasmas. This includes mathematical modelling of solar magnetic flux tubes and processes that heat and maintain the coronal plasma at multi-million degree temperatures; studying fundamental plasma processes such as waves and instabilities in inhomogeneous media; determining the physical parameters of solar magnetic structures.
For online simulations of Kelvin-Helmholtz Instability, Kelvin-Helmholtz Instability with a magnetic field, Orszag-Tang Vortex, MHD Waves propagation in the Realistic solar atmosphere and Validation of MHD Code for Gravitationally Stratified Media on Graphical Processing Units see simulations.
