Paul Resnick is a professor in the School of Information and coordinator of the Community Information Corps. Previously he worked as a researcher at AT&T Labs and AT&T Bell Labs, and as an assistant professor at the Sloan School of Management at MIT.

Professor Resnick's research focuses on SocioTechnical Capital, productive social relations that are enabled by the ongoing use of information and communication technology. His current projects include analyzing and designing reputation systems that help maintain trust among strangers on-line, and using photo-directories and email lists to increase social ties in neighborhoods.

Resnick was a pioneer in the field of recommender systems (sometimes called collaborative filtering or social filtering). Recommender systems guide people to interesting materials based on recommendations from other people. He chaired the PICS Interest Group at MIT's World Wide Web Consortium and was one of the main authors of the PICS technical specifications. PICS, the Platform for Internet Content Selection, provides a common infrastructure for the creation of labeling systems, and filtering software based on those labels.
