Our research activities primarily address fundamental issues in physics and chemistry related to discharges and plasmas in both gaseous and liquid environments. We aim to experimentally determine key plasma parameters such as electric field strength, electron-related properties (including electron distribution function, electron temperature, and density), and the densities of significant plasma species. These investigations are conducted at extremely small spatial and temporal scales using advanced spectroscopic and electrical techniques.
To support our experimental work, we employ analytical models and computer simulations. Numerical modeling plays a crucial role in deeply understanding gas discharge physics and the underlying plasma phenomena. It also allows us to conduct 'numerical experiments' in conditions often challenging or beyond conventional experimental methods' capabilities. Leveraging our profound expertise in plasma physics, our group collaborates with numerous international research institutions and industry partners.
