Dr. Alexander H. Levis is University Professor of Electrical, Computer, and Systems Engineering and heads the System Architectures Laboratory of the Electrical and Computer Engineering department, George Mason University, Fairfax, VA. From 2001 to 2004 he served as the Chief Scientist of the U.S. Air Force, on leave from GMU. He was educated at MIT where he received the BS (1965), MS (1965), ME (1967), and Sc.D. (1968) degrees in Mechanical Engineering with control systems as his area of specialization. He also attended Ripon College where he received the AB degree (1963) in Mathematics and Physics. Dr. Levis is a Fellow of the Institute of Electrical and Electronic Engineers (IEEE) and past president of the IEEE Control Systems Society; a Fellow of the American Association for the Advancement of Science (AAAS) and a Fellow of the International Council on Systems Engineering (INCOSE); an Associate Fellow of the American Institute of Aeronautics and Astronautics (AIAA); and serves on the board of the Educational Foundation of AFCEA. He has received three times the Exceptional Civilian Service medal from the Air Force (1994, 2001, 2004) and the Meritorious Civilian Service medal (2008) for contributions as a member of the Air Force Scientific Advisory Board and as Chief Scientist. He has also received the Air Force Chief's Medallion and the Third Millennium medal from IEEE.

He has taught at the Polytechnic Institute of Brooklyn (1968-1973), headed the Systems Research Dept. at Systems Control, Inc. in Palo Alto, CA (1973-1979), was a senior research scientist at the Laboratory for Information and Decision Systems at MIT (1979-1990), and moved to George Mason University in 1990 where he headed twice the Systems Engineering department. For the last fifteen years, his areas of research have been system architectures including architecture design and evaluation, adaptive architectures for command and control, methodologies for methodologies for multi-modeling and meta-modeling. Current research focus is the application of discrete event system theory to a variety of architecture and command and control problems. He has over 270 publications documenting his research, including the three volume set that he co-edited on "The Science of Command and Control", published by AFCEA, and the "The Limitless Sky: Air Force Science and Technology contributions to the Nation," published by the Air Force. He serves on a number of government advisory boards,

Possible Advisee Scholarly Paper Topics

  1. Dynamics of Discrete Event Systems: There are two sets of methods for the analysis of discrete event systems - structural methods and state space methods. In analyzing systems, one or both types of methods may be used with each one providing different insights into the dynamics of the system. Aseess and compare the two sets of methods and identify the types of insights and answers each set
  2. Evaluation of System Architectures: Discrete event dynamical models, referred to as executable models, have been proposed as a basis for the evaluation of system
  3. Review existing approaches and identify solved problems and unsolved problems that constitute research
