welcome

The signal processing and information networking laboratory (spinlab) was founded in 2002 by Prof. D. Richard Brown 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 is currently provided by the National Science Foundation through an NSF Career award beginning in January 2005. Spinlab has also received prior funding support from DARPA, 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.
