Eric Freudenthal (2004), Assistant Professor. Research Areas: Design and development of self-organizing parallel and distributed systems that provide high performance over a range of operating conditions. Synopsis: Extension of peer-to-peer techniques to achieve robustness and security in self-organizing distributed systems that span administrative domains. Specific interests in techniques for (a) detection and maintenance of localized clusters, (b) construction self-organizing ad-hoc coalitions of systems that provide security, high performance, and robustness, (c) dynamic modulation of service quality and access levels based on connectivity and level-of-authorization, and (d) decentralized access control of systems that expose and therefore are able to reason over partial transitive trust.
