2002-present: Professor of Computer Science, George Mason University; also Director C4I Center from 2005. Teach graduate and undegraduate courses in computer networking and networked virtual environments; lead research teams in Web-based techniques for interoperability of military command and control systems with simulations and in multimedia networking including effective, affordable Internet distance education. Principal Investigator in multiple, multi-organization/multi-year projects in these areas. Projects include "Visible Embryo" project (sponsored by Nation al Library of Medicine) by eight nationally-recognized medical and information technology teams that demonstrated the feasibility of advanced medical collaboration using visualization over high-performance networks across the US; also the Extensible Modeling and Simulation Framework (XMSF) initiative (sponsored by Defense Modeling and Simulation Office) which led to use of Web technologies for inter-operation of military simulation and C4I software systems; currently leader in Battle Management Language (BML) projects including Extensible BML, Joint BML, geoBML, and NATO Coalition BML and related SISO standards effort. Developed MIST/C open-source synchronous Internet distance education software and used it to provide online MS degree programs in Computer Science. Led C4I Center to tenfold growth in project funding.
1992-2001: Associate Professor of Computer Science and Director, Networking and Simulation Laboratory, George Mason University. Taught graduate and undergraduate courses in computer networking; performed research in protocols for application of high performance data networks, focus on network and higher layers to be used for multicast interconnection of distributed simulation. Active in Internet Engineering Task Force (IETF) work in multi-casting technologies; developed Selectively Reliable Multicast Protocol specification and also a suite of models to simulate Quality of Service protocols for the Internet, recognized as one of two top academic projects for 1997 by developers of the OPNET modeling system; served as Principal Investigator leading an eight-member team of GMU faculty and subcontractors for the DARPA Computer Assisted Education and Training Initiative (CAETI) and the follow-on DoDEA Presidential Technology Initiative (PTI); 1995 recipient of IEEE Harry Diamond Memorial Award for developments in networking for distributed simulation. Developer of Network Workbench open source network simulation/educational software. Author of Understanding Internet Protocols. Served in 2000 as Vice President for Technology Policy Activities of IEEE-USA and in 2001 as General Chair of IEEE Distributed Simulation and Real time Applications Workshop. Elected Fellow of the ACM, 2001, for "contributions to information technology in transitioning the Internet from a Federal research project to commercial availability, and development of Internet distance education technologies."
1991-1992: Program Director, Distributed Simulation, Defense Advanced Research Projects Agency (DARPA). Responsible for program planning and execution in distributed war-fighting simulation, a leading-edge activity designated "critical" by the Department of Defense that makes intensive use of computing and communications technologies, with budget of $40 million. Defined, justified, organized, and led advanced technology program to enable distributed simulation as a worldwide Department of Defense capability for readiness, systems acquisition, analysis, and military operations. Personally managed the development of the advanced multimedia worldwide data network and distributed system protocols required for this capability, as well as the Aggregate Level Simulation Protocol (ALSP) project that led to the DoD High Level Architecture (HLA) for modeling and simulation. Retired with rank of Lieutenant Colonel. Received Defense Superior Service Medal on retirement for "achievements in computer systems, networking, and simulation."
1989-1991: Deputy Director, DARPA Information Science and Technology Office and Tactical Technology Office. Responsible for administration in support of about twenty technical professionals working at the cutting edge of information technology. Personally managed programs in high definition imaging systems and advanced networking. Represented DARPA on the team that started the Federal High Performance Computing and Communications initiative. Responsible for transition of DARPA Internet program to private sector commercialization. Elected Fellow of the IEEE for technical leadership in computing systems and networking.
1986-1988: Program Manager for Advanced Computing and Networking, DARPA. Responsible for parallel computing and advanced networking. Built DARPA program that became the basis for much of the Federal High Performance Computing initiative. Leader in creating the Federal Networking Council and in developing plans for the National Research and Education Network that has today grown in concept to become the National Information Infrastructure (NII). Leader in founding the Committee for Coordination of Intercontinental Research Networks (CCIRN) that developed what has become worldwide Internet connectivity.
1985-1986: IEEE Congressional Fellow, U.S. Congressional Staff. Provided technical support for the Computer Security Act and authorizing legislation for the National Bureau of Standards, including pilot program enabling the flexible personnel management of government scientists and engineers.
1981-1985: Associate Professor, Department of Electrical Engineering, U.S. Military Academy, West Point, New York. Developed new course spearheading change to curriculum. Performed research in parallel computing, including cooperative program as part of the RP3 Project on-site at IBM T. J. Watson Laboratory, Yorktown Heights, New York.
Networking and distributed multimedia computing and their application to distributed education and training.
