Conrad Bock (Fed)

Conrad Bock is a Computer Scientist Systems in NIST’s Communications Technology Lab performing research in Smart Connected Manufacturing Systems.  He is currently project leader for integrating systems engineering and analysis models (SAI), leading research and standardization in interoperability between modeling languages used in systems engineering and specialized engineering disciplines, such as 1D simulation and logical verification of behavior models.

He specializes in engineering information language formalization, focusing on representation of system behavior and assembly, and facilitating capture of implicit knowledge. His work leverages ontology-based language development, as in OWL and the Process Specification Language (PSL), a first-order axiomitization of processes supporting automated consistency checking of rules against processes. He used PSL to develop the first standard formalization of UML.  This led to his development of an ontology modeling architecture now used as the basis for a major upgrade to the Systems Modeling Language (SysML), the most widely-used graphical language for systems engineering, currently being prepared for Object Management Group (OMG).

Mr. Bock is a past chair of the OMG Revision Task Force for SysML, versions 1.3 and 1.4, and one of the primary contributors to the Unified Modeling Language (UML) at OMG, most widely-used graphical language for software and the basis for SysML.

He was a significant contributor to a major upgrade to the Business Process Model and Notation (BPMN), a with improvements for modeling interaction between businesses or parts of a business. He led the development of semantics for public process modeling, and integrating interactions with internal business processes. He also led development of a UML extension for BPMN Processes, to improve interoperability between process and software modeling.


Mr. Bock received two U.S. Department of Commerce Bronze Medals and an International Council on Systems Engineering Outstanding Service Award for work on developing and formalizing systems engineering information languages.
