Dr. Williams joined the ECE faculty in 1989, where he is affiliated with the Center for Signal and Image Processing. He most recently served as the associate chair for ECE Undergraduate Affairs from 2003-2011 and as interim school chair from July 2011-August 2012. He received the BSEE, MS, and PhD degrees in electrical and computer engineering from Rice University in 1984, 1987, and 1989, respectively.

Dr. Williams' research interests involve the application of statistical signal processing methods to communications, radar signal processing, and the study of nonlinear dynamics. He is a member of the IEEE Signal Processing Society's Board of Governors, Signal Processing Theory and Methods Technical Committee, and Signal Processing Education Technical Committee. Dr. Williams is currently Special Sections Area Editor for the IEEE Signal Processing Magazine and was co-editor of The Digital Signal Processing Handbook (CRC Press and IEEE Press, 1998). He is a member of the Tau Beta Pi, Eta Kappa Nu, and Phi Beta Kappa honor societies.
