Personal Bio

Mark Hartong currently works in the Cyber Warfare Systems Group at the Johns Hopkins University Applied Physics Laboratory (APL), where he provides systems engineering and operational subject matter expertise related to the acquisition and development of cyberspace operations capabilities. This includes requirements analysis, architecture development, systems engineering, mission analysis, and cyber capability assessments. He is also a member of the Transportation Research Board of the National Academy of Sciences, where he promotes innovation and progress through fundamental research in transportation policy, communications, cybersecurity, systems engineering, test, and evaluation.

Previously Dr. Hartong was employed as the Senior Scientific Technical Advisor at the Federal Railroad Administration, US Department of Transportation where he served as the agency’s senior technical authority on the application of safety and security critical electronics and software for use in the railroad environment.   Before joining the Federal Railroad Administration, he was a Staff Systems Engineer with Lockheed Martin Corporation providing systems engineering support for a wide range of classified and unclassified communications hardware and software development programs exploring state of the art communications systems and networking technologies.  Prior to his employment at Lockheed Martin, he served on active duty in the US Navy as a naval engineering duty officer.  As a navy line technical specialist qualified in submarine warfare, he provided technical, acquisition and fleet industrial leadership to meet national defense needs of fleet units and their associated warfare support systems.  This covered hull, mechanical, electrical, combat and weapon systems as well as command, control, communications, computers, and intelligence systems.

Dr. Hartong received his BSc in Mechanical Engineering from Iowa State University with an emphasis in systems and computer aided design.  He received a MSc in Computer Science from the US Naval Postgraduate School where his thesis was analyzing the performance of the S-1 Multiprocessor at Lawrence Livermore National Laboratory in conducting spread spectrum signal analysis and detection for intelligence community applications.  He received an MSc in Software Systems Engineering, a graduate certificate in Information Security and his PhD in information technology from George Mason University.  His doctorate is in the interdisciplinary field of Information Technology with a concentration in Cyber Security and Cyber-Human Systems.  This encompasses computer science, software engineering, electronics/computer engineering, communications engineering, operations research, and security.  His doctoral dissertation was on Secure Communication Based Train Control (CBTC) Operations.  CBTC systems are cyber physical control systems that provide continuous, automatic train control, supervision, and operation.  Dr. Hartong is also a registered professional engineer.
