**About the Editor**

**Dirk Uhrlandt** has been with the Leibniz Institute for Plasma Science and Technology e.V. (INP Greifswald) in Germany since 1993. At present, he is the head of the research division "Materials and Energy" and a scientific board member of the INP. He is also a full professor of high current and high voltage engineering at the Faculty for Computer Science and Electrical Engineering of the University of Rostock, Germany, since 2017. He received his Ph.D. in theoretical physics from Greifswald University, Germany, in 1997. His main research interests are the physics and application of thermal plasmas. This includes arc behavior and arc–electrode interaction in vacuum interrupters, in high-voltage circuit breakers and arrestors as well as in low-voltage switchgear. He is also interested in arc behavior and material transfer in arc welding processes. His work comprises optical diagnostics including emissions and absorption spectroscopy, as well as the magneto-hydrodynamic simulation and non-equilibrium modeling of arcs.
