With over 25 years of experience, John Tatar is responsible for designing, developing, implementing, and operating computational and network infrastructures at Argonne National Laboratory.
While at Argonne, Tatar was assigned to the United States Air Force/Europe Warrior Preparation Center in Einsidlerhof, Germany to assist in the development of database applications and system engineering to prepare computer-aided exercise scenarios for NATO Battle Staff. Tatar was employed by a major metropolitan transportation agency to develop a network design to support a distributed sensor and emergency response system, along with other operations applications. The network simulation tools were utilized to evaluate potential network failure modes and quality of service. He was also the project lead for the development of a monitoring system for components of a system to alert operators of any system component failures.
Tatar participated in a multi-laboratory team to design, develop and implement an integrated biological hazard analytic system for state, county and municipal public health departments. He and fellow team members integrated all the system components on to a stand-alone system and coordinated with various local government entities on the integration of the system into their public health operations. In the past, Tatar has worked with a number of other organizations in the design, development and implementation of computational and network infrastructures.These include the U.S. Joint Chiefs of Staff/J-8 Directorate, U.S. Air Force Europe, Combined Forces Command Korea and the Fort Huachuca Network Enterprise Center.
