George Edwards

Welcome to my homepage.

I'm a Ph.D. candidate in the Computer Science Department at the University of Southern California. I'm also a USC Viterbi School of Engineering Fellow, an Annenberg Graduate Fellow, and a member of the Software Architecture Research Group in the Center for Systems and Software Engineering. My Ph.D. advisor is Nenad Medvidovic.

Prior to attending USC, I received my B.S. from Vanderbilt University, spent one year in the M.S. program at Vanderbilt, advised by Dr. Douglas C. Schmidt, and worked as a research assistant at Vandy's Institute for Software Integrated Systems.

I've held several research and engineering positions outside of academia. During 2005-06, I worked as a software architect for The Boeing Company on the Future Combat Systems (FCS) project, and during the summer of 2008, I was a research intern in the Mobile Service Products group at IBM Research. In addition to pursuing my Ph.D., I am currently a part-time research scientist at Intelligent Systems Technology, Inc.

My research interests include varied topics related to software engineering and distributed systems, such as model-driven technologies, middleware platforms, application frameworks, and mobile software systems.

Research Projects

Here are some of the projects I'm working on right now.

The eXtensible Tool-chain for Evaluation of Architectural Models (XTEAM) implements a model-driven engineering (MDE) approach to software architecture that combines extensible modeling languages based on architectural constructs with a model interpreter framework that enables rapid implementation of customized dynamic analyses at the architectural level. XTEAM consists of a suite of architecture description language (ADL) extensions and model transformation engines targeted specifically for highly distributed, resource-constrained, and mobile computing environments. XTEAM model transformations generate system simulations that provide a dynamic, scenario- and risk-driven view of the executing system. XTEAM provides the extensibility to easily accommodate both new modeling language features and new architectural analyses. Learn more...

Prism-MW is a middleware targeted at applications in highly distributed, resource constrained, heterogeneous, and mobile settings. The key properties of Prism-MW are its native, and flexible, support for architectural abstractions (including architectural styles), efficiency, scalability, and extensibility. By adopting an explicit architectural perspective, Prism-MW has inherited the separation of computation (handled by components) from interaction (handled by ports and connectors) intrinsic to software architectures.
