Research Overview

Mobile Computing - Act as Principal Investigator for a project to investigate cooperative techniques for management of dynamic data in a personal area network. Implemented a performance measurement tool for mobile devices. Contributed to the design of Turducken, a mobile device that combines several mobile computing platforms into a single, power-efficient device. Contributed to the design of Triage, a software architecture to support power-efficient operation of tiered hardware for microservers.

Peer-to-Peer Computing - Designed, implemented, and performed simulated evaluation of a power-aware technique for maintaining data availability in a personal area network. Designed and performed simulated evaluation of a one-to-many data distribution architecture for peer-based networks. Co-authored a frequently-cited survey of the field of peer-to-peer computing.

Internet Technologies - Designed and implemented a system to analyze an XML schema and produce a set of customized application components. Contributed to implementation and evaluation of an algorithm to support eager scheduling of tasks in an Internet-based parallel computing system. Designed and implemented a model for supporting scalable web services and dynamic user interaction using one-to-many data distribution. Redesigned and implemented a transcoding engine that performs document transcoding based on pattern matching rules.

Educational Technology - Designed and deployed a digital classroom to support presentation, remote access, and archival of presentations and content presented. Developed a set of best practices for deploying future digital classroom spaces.
