Klaus Bohnert has been a Senior Principal Scientist at the ABB Corporate Research Center in Baden, Switzerland. He received a Ph.D. degree in physics from the University of Karlsruhe (now KIT), Germany, in 1981. Subsequently, he was a postdoctoral research scientist in the field of optical sciences at the University of Frankfurt and the University of North Texas. In 1986, he joined the Brown Boveri Corporate Research Center (ABB Ltd since 1988) in Baden, Switzerland. There, his focus was on research and development of optical sensors for applications in the electric power industry, oil and gas industry, and chemical process industries. He has been an author or co-author of more than 130 scientific journal articles, about 130 conference presentations, and an inventor on over 90 patents.
