Malcolm Smith received the B.A. (M.A.) degree in mathematics, the M.Phil in control engineering and operational research and the Ph.D. degree in control Engineering from the University of Cambridge, England. He was subsequently a Research Fellow at the German Aerospace Center, DLR, Oberpfaffenhofen, Germany, a Visiting Assistant Professor and Research Fellow with the Department of Electrical Engineering at McGill University, Montreal, Canada, and an Assistant Professor with the Department of Electrical Engineering at the Ohio State University, Columbus, USA. He is now a Fellow of Gonville and Caius College and a Professor in the Department of Engineering at the University of Cambridge. He received the 1992 and 1999 George Axelby Best Paper Awards, in the IEEE Transactions on Automatic Control in 1992 and 1999, both times for joint work with T.T. Georgiou. He is a Fellow of the IEEE and the Royal Academy of Engineering.

Current Research Interests

Robust control, passivity based control, circuit synthesis, mechanical networks, mathematical systems theory, nonlinear systems and automotive applications.
