Johannes Gruenwald obtained his PhD in experimental plasma physics at the University of Innsbruck in 2012 on the topic of electrical probe diagnostics of plasma fireballs. Afterwards he worked on an industrial project in cooperation with the University of Graz, which was dedicated to develop large area coating technologies for carbon based materials. From 2013 to 2017 he was working at the Leibniz Institute for Plasma Science and Technology (INP) in Greifswald, Germany and at the Extreme Light Infrastructure (ELI) in Prague, Czech Republic. In 2018 he became the CEO of Gruenwald Laboratories a consulting and research company specialised in plasma science and technology. He has authored or co-authored about 50 publications in different fields of plasma physics, ranging from diagnostics over instabilities to coating and fusion technology. Furthermore, he is editor-in-chief of the Journal of Technological and Space Plasmas and holds an international patent for large area coatings with inverted plasma fireballs.
