Research interests
- Plasma turbulence and transport
- Mesoplasma dynamics
- Nonlinear dynamics
- Fluid mechanics including multi-phase flows
Current research
- Global numerical simulations of electromagnetic turbulence and transport in tokamaks with special emphasis on simulations of MAST, COMPASS and JET (ultimately, ITER) plasmas in relation to strong rotation, pellets, transients and profile-turbulence interaction on the mesoscales
Dr Thyagaraja has been motivated throughout his research career to seek the “answer” wherever it may be found and to construct theoretical models to understand and interpret and ultimately develop the ability to predict the outcomes of real experiments and observations.
He has also been deeply interested in teaching and explaining difficult scientific/mathematical concepts to non-scientists, both in his official capacity and as a “Science and Engineering Ambassador” for SET/Oxford Trust over the last 15 years.
He considers that his published papers, students and lectures represent his career achievements and must speak for themselves.
