Dimitrios Kaltsas, Ph.D.

I am a postdoctoral researcher at the Department of Physics, University of Ioannina, Greece. My research interests focus on the study of equilibrium, stability, and dynamics of laboratory and astrophysical plasmas using Hamiltonian fluid dynamics, kinetic and hybrid models, as well as neural networks and machine learning methods. I am particularly interested in the Hamiltonian construction of new hybrid fluid-kinetic models characterized by consistent conservation laws that have applications in the study of magnetic confinement of plasma in fusion reactors such as the tokamak and in phenomena related to astrophysical plasma like magnetic reconnection. I am also interested in the application of computational methods that obey conservation laws and deep learning methods to solve the differential equations arising in these models. In parallel with my postdoctoral research at the Department of Physics of the University of Ioannina, I have independently taught a significant number of courses at the International Hellenic University and the Department of Physics of the Democritus University of Thrace from 2020 to 2024 and have participated in the supervision of undergraduate and postgraduate theses.
