David R. Karger David R. Karger is a Professor of Electrical Engineering and Computer Science at MIT's Computer Science and Artificial Intelligence Laboratory. He earned his PhD at Stanford University in 1994, and has since done research in a variety of areas including algorithms, machine learning, information retrieval, coding and communication, networking, peer to peer systems, and human-computer interaction. A constant interest, however, has been to make it easier for people to create, find, organize, manipulate, and share information. To this end he organized the Haystack group and led the development of a system of the same name. The Haystack system was one of the first "semantic desktops", using a semantic-web underlay to provide end-users with a unified information management application for their personal information. His group continues to research tools and techniques to help end-users manage information. He is also one of the PIs on MIT's SIMILE project, a collaboration developing semantic-web tools to improve the management and retrieval of information at the institutional level.
