Simulation engineering is an establishing discipline for developing, employing and maintaining simulations using the fundamental theories of simulation science. I have been practicing this engineering discipline more than 10 years; establishing methodologies and work flows, and developing tools and infrastructures. I am currently participating in Flight Dynamics and Simulation Department of German Aerospace Center (DLR) Institute of Flight Systems as a Research Scientist. I am a part of the team that is responsible for the Air Vehicle Simulator (AVES). Here I am conducting simulation engineering research on application of model based methodologies for flight simulations and simulation-based methodologies for flight systems development.  


  • Model-based simulation engineering: Application of model-driven practices in simulation engineering lifecycle.
    • Simulation metamodeling, model transformations, code generation
    • Model-based testing, model-driven development, model-based scenario development, model-based modernization
  • Simulation-based systems development: Methodologies and approaches for streamlining the simulation utilization in system development.
    • X-in-the-loop testing, model integrations, FMI, simulation scenarios for systems validation, distributed simulation, simulation continuity  
  • Ontologies in simulation: Methodologies and integration strategies for ontologies in order to introduce them as the implicit components of simulation toolchain
    • Ontologies for simulation metamodeling, ontologies for domain modeling, life cycle ontologies
