Klaus-Dieter Weltmann is the Chairman of the Board and Scientific Director of the Leibniz Institute for Plasma Science and Technology e.V. (INP), He received his PhD in applied physics working on nonlinear dynamics in low temperature plasmas. In 1994, he was Visiting Scientist at West Virginia University. In 1995, he joined ABB Corporate Research Ltd., Switzerland, working on the development of switchgear. In 1998, he became the head of the High Voltage Systems Group of ABB. In 2000, he was appointed to lead the Research & Development unit Gas Insulated Switchgear at ABB High Voltage Technologies Ltd., Switzerland and later in 2002, he became Business Unit R&D Manager. Since 2003 he is Director of the Leibniz Institute for Plasma Science and Technology e.V. Since 2005, Weltmann investigates the use of plasmas in the field of life science with a special focus on the innovative field of plasma medicine. He initiated two major projects (ZIK plasmatis, Campus PlasmaMed) as well as the foundation of the "National Center for Plasma Medicine" in 2013, which bundles all plasma medicine activities in Germany. In cooperation with the University of Greifswald, Weltmann initiated and filled the world's first professorship in plasma medicine. Internationally, Weltmann is co-founder and co-director of the Applied Plasma Medicine Center in Seoul (Korea). Weltmann built up external branches of his institute at the University of Rostock and the Clinical Centre of Karlsburg, involving local partners. Following his innovative concept, physicists, biologists, chemists, engineers and medical doctors are gathered for cooperation within the clinical centres under the same roof. Weltmann co-edited the book "Comprehensive Clinical Plasma Medicine. Cold Physical Plasma for Medical Application", published by Springer in 2016. He was awarded the Plasma Physics Innovation Price of the European Physics Society in 2014 for his outstanding contributions to plasma physics, particularly in the field of Plasma Medicine. Other current main projects driven by Weltmann at INP cope with Plasma Agriculture ("Plasma for Food") and new methods and technologies for energy storage (Campfire). They benefit of important funding from the Federal Republic of Germany. Weltmann helds more than 45 patents. He aims to push the transfer of developed prototypes to products. This purpose is mainly pursued by the 5 institute's spin-offs.
