Awards and Honors

Winser has received many awards including the following:

1. In June 1993, Winser received the American Society for Engineering Education (ASEE) Minorities in Engineering Award for Leadership in the Conception, Organization and Operation of Precollege and College Activities to Increase Participation of Minorities in Engineering.
2. In September 1998, Winser received the Presidential Award for Excellence in Science, Mathematics and Engineering Mentoring from the White House Office of Science and Technology and National Science Foundation.
3. In March 2000, Winser received the Dr. Janice A. Lumkin Educator of the Year Award from the National Society of Black Engineers (NSBE).


Winser Alexander's research spans the areas of digital signal processing, image processing, parallel algorithms, and parallel computer architecture. His current research program involves the development of high performance algorithms for digital signal processing, image processing, pattern recognition, and computational engineering. Winser and his colleagues have developed a paradigm called the Block Data Flow Paradigm for implementing algorithms such as 1-D and 2-D digital filters, the DCT, the 1-D and 2-D wavelet transform, LU decomposition, QR decomposition, etc. on a multiprocessor system. They have developed a multiprocessor architecture called the Block Data Parallel Architecture (BDPA) that can use this approach to achieve almost linear speedup, high throughput and high efficiency for these algorithms.

Winser served as the Director of Graduate Programs for the ECE Department from August 1988 to May 1997 and from June 2001 to August 2002. He has developed graduate courses in Multidimensional Digital Processing and DSP Architecture, and he teaches courses at the undergraduate level in Logic Design and Digital Signal Processing.
