Author Biography

Mark N. Horenstein is a Professor in the Department of Electrical and Computer Engineering at Boston University. He has degrees in Electrical Engineering from M.I.T. and U.C. Berkeley and has been involved in teaching engineering design for the greater part of his academic career. He frequently teaches first-year engineering courses, and he also devised and developed his department's senior capstone design course. In the latter, students work for a virtual engineering company developing products and systems for real-world engineering and social-service clients. Professor Horenstein does research in the areas of electromechanical design and applied electromagnetics.
