During a long career in engineering research and education, Krogh established himself as an expert in the design and applications of computer control systems and helped bring graduate-level education to Africa. Early in his engineering career, Krogh worked for the energy systems division of Westinghouse Electric Corp., designing software for utility control centers. After completing his doctorate in electrical engineering, he joined the engineering faculty of Carnegie Mellon University in Pittsburgh. As a young researcher, he was awarded the Presidential Young Investigator Award by the National Science Foundation. The professor’s research projects with government and industry included smart grid technology, mobile robots, semiconductor manufacturing, automotive power trains and aircraft flight control systems. As a final act in his career, Krogh moved to Rwanda to become founding director of Carnegie Mellon University-Africa, a branch of the school’s engineering college. It was the first program of its kind on the continent of Africa, with resident faculty offering the same master’s degrees in information technology and electrical and computer engineering as the main campus. Krogh led the program for six years, seeing nearly one hundred graduates begin technical careers in Africa before he retired in 2018.
