Program

James E. Coolahan, Ph.D., is the Chief Technology Officer of Coolahan Associates, LLC, having retired from full-time employment at the Johns Hopkins University Applied Physics Laboratory (JHU/APL) in December 2012 after 40 years of service. Dr. Coolahan chaired the M&S Committee of the Systems Engineering Division of the National Defense Industrial Association from 2010 through 2016, and chaired the Conference Committee of the Simulation Interoperability Standards Organization in 2016-17. He teaches short courses on M&S in Systems Engineering, and also teaches semester-long courses in M&S in Systems Engineering in the JHU Engineering for Professionals M.S. degree program. He holds B.S. and M.S. degrees in aerospace engineering from the University of Notre Dame and the Catholic University of America, respectively, and M.S. and Ph.D. degrees in computer science from JHU and the University of Maryland, respectively.
