Dmitry A. Sorokin received the Ph.D. degree from the Physics Department, National Research Tomsk State University, Tomsk, Russia, in 2009. He is currently the Head of the Laboratory of Optical Radiations, Institute of High Current Electronics, Siberian Branch, Russian Academy of Sciences (IHCE SB RAS), Tomsk. In 2015, he defended his Ph.D. thesis. He has authored or co-authored over 80 publications. Research interests: physics of a gas discharge, optics, physics of low-temperature plasma, and spectroscopy of low-temperature plasma. He made a contribution to the field of studies of high-voltage nanosecond discharges initiated by runaway electrons: the electrical properties of such discharges, the properties and parameters of the plasma, and the properties of runaway electron beams.
