George Edwards Welcome to my homepage. I'm a Ph.D. student in the Computer Science Department at the University of Southern California. I'm also a USC Viterbi School of Engineering Fellow and an Annenberg Graduate Fellow. I joined the Software Architecture Research Group at USC in the fall of 2004 with Nenad Medvidovic as my advisor. In the spring of 2006, I received my M.S. in Computer Science from USC, and in the spring of 2008, I passed my qualifying exam and was admitted to Ph.D. candidacy. Prior to attending USC, I received my B.S. from Vanderbilt University and spent one year in the M.S. program at Vanderbilt, advised by Dr. Douglas C. Schmidt. During 2005-06, I also 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. My research interests include software architecture, mobile and embedded systems, and middleware. 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.
