Dr. Uwe Ritschel studied physics and received his Ph.D. in 1989. After several years in fundamental research in 2000, he joined the engineering department of Nordex, a wind turbine manufacturer. In 2002 he established the Windrad Engineering Gmb H and worked as managing director. The main business is the development of new wind turbines for international customers from the wind industry. Since 2014 he works as the Chair of Wind Energy Technology at the University of Rostock. In 2019 he co-founded the independent research institute IWEN working more generally on renewable energies and energy transition.
Dr. Michael Beyer received his Ph.D. in physics in 1985. He held several research and teaching positions in different countries including Germany, U.S.A., Switzerland, and several visiting and research grants on basic research. He is affiliated to the University of Rostock since 1994. In 2008 he entered the wind business and from 2014 until 2021 he was managing director of Windrad Engineering Gmb H, an independent engineering office and design house for wind turbines. He shares his experience through supervising, consulting, and is presently teaching mechanical aspects of wind energy at the University of Kassel.
