welcome

The signal processing and information networking laboratory (spinlab) was founded in 2002 by Prof. D. Richard Brown III with the purpose of bringing motivated undergraduate and graduate students together to work on fundamental and applied problems in signal processing, communication systems, and networking. Spinlab is located on the third floor of the Atwater Kent Laboratories building at Worcester Polytechnic Institute.

Spinlab funding has been provided by National Science Foundation, Army Research Office. DARPA, Raytheon BBN Technologies, Bose, Inc, and General Electric Industrial Systems. The generous support provided by these sponsors has funded the degrees of several graduate students as well as the senior project work of dozens of undergraduate students. If you are a student interested in working in spinlab, please click on the Opportunities link above.

The spinlab web site is written in HTML and CSS and looks best when viewed with a standards-compliant browser like Chrome, Firefox, Opera, or Safari.
