"Dr Darren" has been teaching and applying SysML for Model-Based Systems Engineering for over 20 years, and is one of the world's most active promoters of SysML for MBSE. He originally trained as a physicist (astrophysics, radioastronomy, particle accelerators) and first applied SysML to modelling of radio-telescopes and neutron beam instruments in the earliest days of SysML. He is a former Expert Advisor for Science, Education, and Engineering to No Magic Inc, original developers of the SysML Plugin for MagicDraw/Cameo. He is the developer of the Webel Parsing Analysis recipe for traceable elicitation of SysML models from engineering documents. He has applied SysML to modelling of as many real projects as anyone on the planet. And he just LOVES port-based engineering and simulation with SysML!
