Research

Dr. Williamson joined IIT in August 1989 and is currently Professor in the Department of Electrical and Computer Engineering.

Dr. Williamson's research interests include system identification and parameter estimation as applied in the areas of signal processing, control, and biomedical applications. He is also active working in the area of control of power electronic systems.

Dr. Williamson has previously served as the Associate Dean for Academic Affairs in IIT's Graduate College and as the Graduate Program Director for the Department of Electrical and Computer Engineering. He was an Associate Editor in digital signal processing for the IEEE Transactions on Circuits and Systems Part II. He is a Senior Member of the Institute of Electrical and Electronics Engineers, and he is a member of Eta Kappa Nu and Tau Beta Pi.
