Scientific Activities:
- Main fields of research: Theory of electromagnetic processes in plasma (emission and absorption of electromagnetic radiation by plasmas and plasma-like media); Physics of gas discharges (arc, optical discharge, etc.) and their applications for welding, cutting, surfacing, spraying and other technologies of material processing.
- Current research interests: Development
of combined laser-arc processes for joining and treatment of materials,
including theoretical investigation and computer modeling of focused
laser radiation and arc discharge plasma interaction, as well as their
combined affecting the different materials; development of software
for computer-aided simulation of plasma technologies.
