Doohwan Kim, Ph.D.     President, Founder

Dr. Kim manages operations of RTSync and coordinates the team's efforts to develop modeling and simulation based commercial products to support interoperability testing and evaluation. He is a member of Data Strategy and Data Engineering task group at the Joint Interoperability Test Command, Ft. Huachuca, AZ, where he is currently leading the team to develop agent-based test instrumentation infrastructure for the U.S. Department of Defense Net-centric Enterprise Services over Global Information Grid. He has conducted research and development on complex large scale systems integration problems and led many software development projects. He currently holds Research Professorship at the University of Arizona and is an associate of Arizona Center for Integrative Modeling and Simulation (ACIMS). Previously, Dr. Kim was a research staff member at IBM T. J. Watson research center, NY. He received his Ph.D. degree in computer engineering from the University of Arizona.

Bernard Zeigler, Ph.D. Chief Scientist

Dr. Zeigler is Professor Emeritus of Electrical and Computer Engineering at the University of Arizona (UA) and Research Professor in the C4I Center at George Mason University, is internationally known for his seminal contributions in modeling and simulation theory. He has published several books including “Theory of Modeling and Simulation” and “Modeling & Simulation-Based Data Engineering : Introducing Pragmatics into Ontologies for Net-Centric Information Exchange.” He is well known for the Discrete Event System Specification (DEVS) formalism that he invented in 1976 and which is now being used world-wide in advanced information systems. In 1995, he was named Fellow of the IEEE in recognition of his contributions to the theory of discrete event simulation.

He has given numerous keynote talks, tutorials and short courses, and organized symposia and conferences that were the first to promote modeling and simulation fundamentals and theory. His 1979 foundational article, co-authored with Tuncer Oren, Concepts for advanced simulation methodologies, has become one of the most cited articles in Simulation. His autobiographical retrospective on the evolution of the theory of modeling and simulation appeared in the International Journal of General Systems. (Vol. 32 (3)).
